The capacitors allow the signal to pass through, while 'blocking' the DC voltage level that the signal is 'riding' on. Are you asking to remove the capacitor and connect it straight through? If you had a multistage amplifier, then the DC riding voltage would try to get amplified as well, and the next stage amplifier would probably 'max out' and you'd wind up with just solid DC output, or components further along in the circuit could be damaged.
If you're asking if the capacitor was taken out (like if it blew) then no signal would get through.

∙ 12y agoIf you remove the supply bypass capacitor, chances are the amplifier just won't work.
If you remove the emitter bypass capacitor of the amplifier, DC gain remains unaffected while AC gain increases within the passband. Note though, that the passband is affected by removing/adding the emitter bypass capacitor.
Hope this helps :)

What is the difference between with capacitor rectifier and without capacitor rectifier?
To know the difference between capacitor and non capacitor rectifiers one must study what is the function of filter part.the filter part consists of capacitors or inductors or combination of both. the output of a simple diode rectifier is pulsating dc which means it consists of both dc part and ac part. filters are used to remove the ac part from such an output. capacitor filter means that a capacitor is used for filtering out the ac part. non capacitor or inductor filter means that an inductor is used for filtering out the ac part. There is another type called pii filter where both inductor and capacitor are used. Pii filter is the best kind of filter available

Why inductor alone cannot be used in a filter circuit?
it can be used alone dc welders often just have inductor for filter sometimes diodes go directly to an inductor this will lower the current seen by the diodes and the power source if the diodes go directly to the capacitor the current approaches infinity in the first cycle. the number of inductors and capacitors in the filter remove more and more ac component multistage filters are getting rather rare,a power transistor and a heat sink cost less than capacitors and inductors
What is the use of filter circuits?
A filter circuit is an electronic circuit made using capacitors and inductors. It is designed to produce a restriction on the frequency-bandwidth of an alternating input signal - such as, for example, a wireless/radio signal - to produce a narrower frequency- bandwidth as its output. Another common use of an electronic filter circuit is to remove most of the ac ripple which remains in the output of a diode-based ac rectification circuit so that the resulting is of better quality.
How do you remove a capacitor from a circuit board?
Correct method:Two pieces of equipment are needed. A small wattage soldering iron and a desoldering tool. Heat the junction point up until the solder melts. Use the desoldering tool to remove the melted solder. Do the same thing to the other sideof the capacitor by heating and removing the solder. The capacitor should nowpull away from the PC board.=====Lazy method:--One piece of equipment is needed. A small wire cutter.-- Select one end/side of the capacitor. Position the jaws of the tool oneither side of the wire emerging from it. Then cut.-- Position the jaws of the tool on either side of the intact wire emergingfrom the opposite end/side of the capacitor. Then cut.-- The capacitor should now pull free of the terminal strip or printed board.

What is the effect on voltage gain in a common emitter amplifier when the decoupling capacitor is removed?
The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.
How do I test a capacitor when I cannot remove it out of circuit?
You cannot. It must be taken out of the circuit and then tested on its own.That's not 100% true because, if it has wires at its ends, you can cut through one wire with an appropriate tool and then test the capacitor "out of circuit". If the capacitor is ok you can then re-join the two cut wire ends by applying a blob of solder carefully. (But, to avoid damaging the capacitor, use a suitable heat sink to shield the body of the capacitor from the heat of the soldering iron.)With direct current a capacitor also works like a special type of resistance. Whilst being charged up, it will show low resistance. As it slowly (or quickly) charges, the resistance will grow larger and larger. Whenever I repair circuitry and I have doubts about a capacitor (in the uF area) I simply use my multimeter on its Ohms setting. If a capacitor has shorted, then the result will be 0 Ohm. If the capacitor is working, or partially working, the resistance will gradually increase until it is out of range of the multimeter.Use an ohm-meter first to test the on-board capacitor and then use it to test a similar capacitor off-board, to see if the results sort of match up.Most often they will not match completely as on-board you also measure the effect of all other components connected into circuit with the capacitor. It might point you in the right direction though.On a separate thought, if you really cannot remove it, or disconnect one of its connections, then why test it at all? If it really can't be removed to replace it, then it makes no sense to test it!A capacitor can be tested using multimeter without removing it from circuit. but in order to check it, its polarities should be noted and then keep the positive terminal of multimeter on positive of capacitor and negative terminal on negative. It is vital to note that the readings will be affected by the remainder of the circuit. To test for capacitor function in circuit demands a good understanding of the circuit operation.Of course there are ways to test capacitors, both in circuit and out. While a truly accurate test involved taking the cap out of circuit, a basic test can certainly be done in circuit.Out of circuit, one can either connect to a VM, or better yet, an oscilloscope, and measure the time for voltage to decay to zero across the capacitor. This time should equal the time given by the equation for the time constant, and is dependant on the values associated with that particular capacitor.For RC circuits, this equation equals:τ = R × C. It is the time required to charge the capacitor, through the resistor, to 63.2 (≈ 63) percent of full charge; or to discharge it to 36.8 (≈ 37) percent of its initial voltage. These values are derived from 1 − e − 1 and e − 1 respectively.It is important to keep in mind that one must apply a voltage across the capacitor at its rated value. Thus, if it is a 400V capacitor driving a tube amp, for instance, it must be driven at around 400V. Driving it at 12V will lead to useless results.The only proper way to check for a capacitor value and or leakage is with a proper test bridge: set it to the capacitor's DC rating with it removed from the circuit completely. Any other way is just waste of time.Additionally, a common in-circuit test for a electrolytic capacitor is to measure its Equivalent Series Resistance (ESR) which can be done with an ESR meter. This is a quick and easy way to locate failing electrolytic capacitors, especially in power supply circuits.An effective method of testing any component in-circuit is with an in-circuit curve tracer. If you have an oscilloscope with X-Y input mode you can easily build one of these on your own. They do take some getting used to before you can use it effectively and are most useful for good board vs. bad boardcomparison.
