connections are to be made per the crkt
the main of this crkt is to make strong or to bost the signal
comming to the crkt input is given with ac supply and they are connected to resistor and capacitor when the ac suppply is given it contains slight amount of dc supply so to block the dc supply capacitor is used and the dc supply is given at the collector so that resistor present at c and ground gets biased then another capacitor used at c to ground for removing the dc supply then out put seen on cro across collector to ground we get the perfect amplified signal
the more we give the coupled amplifer the most amplfed sgnal we get

∙ 9y agoA multistage RC coupled amplifier is used when a single amplifier is not sufficient. This is obtained by connecting the output of the first amplifier which is connected to form input of a second amplifier, whose output becomes input of the third amplifier.

What are charactersitics of two stage common emitter amplifiers?
less current flowing through them
Working of RC coupled amplifier?
In a two stage RC coupled amplifier, the two transistors are identical and a common power supply is used. The input is provided to the first stage of the amplifier where it is amplified and this output is used as input for the second stage. This is amplied once again by the other transistor in the second stage and the final output is obtained. There will be a 180 degree phase shift after the first stage amplification which is nullified by the 180 degree phase shift of the second stage amplification.Thus, we obtain an output which is an amplified signal of the input and is in phase with the input signal.
What are the applications of RC coupled amplifier?
They are widely used as voltage amplifiers (ie. In the initial stages of public address systems) because of their excellent audio-fidelity over a wide range of frequency. However because of poor impedance matching this type of coupling transistor circuits is rarely employed in final stages
What is a transformer-coupled class A amplifier?
A transformer-coupled class A amplifier is just what it says it is. You'll recall that a class A amp is one that has an output that varies through all 360 degrees of an input signal. As regards the manner in which the signal is coupled to or from the stage, a transformer is used, complete with the non-linearity that it will introduce because of the characteristics of the (untuned) inductive component.
What is an AF amplifier?
AF means audio frequency. Audio Amplifiers can be subgrouped as voltage amplifiers (or pre-amplifiers) and power amplifiers. The voltage amplifier will raise the level of level of the output of a microphone from say 1 mV to 500mV or 1V. The power amplifier will be the interface between this and the load, which is a speaker. The resistance of the speaker is often 4 ohm or 8 ohm. You cannot have a speaker with 1k as resistance! As such to get say 8W output, an amplifier providing 8V will have to pump 1 amp into an 8 ohm speaker. Thus power amplifiers will have to drive a lot of current into the load. Voltage amplifiers cannot do this. A power amplifier sometimes just has unity voltage gain, but has ability to drive a lot of current into the load. Typical power amplifiers are operated in class B, where for 50% of the signal swing, one transistor provides current, and for the other 50%, the other transistor in a class B provides current into load. Class B amplifiers have cross over distortion, But this can be overcome by pre-biasing, or making the stage operate as class AB. The power amplifiers can also be used to power low resistance loads such as a step up transformer.
What is circuit coupling?
A coupling circuit connects the output of one stage of a system to the input of another stage. There are many different types of coupling circuits (e.g. direct coupled, resistor coupled, capacitor coupled, transformer coupled) each with its own advantages and disadvantages.
What do mean voltage amplification?
It's voltage that's being amplified by a voltage amplifier. Small changes in voltage at the input of the stage cause large changes of voltage at the output of the stage. That larger signal is then coupled out. The stage is said to have amplified the signal, amplified its voltage. And the stage's gain is a measure of how much. This is the simple answer. A further investigation into amplifiers and the underlying ideas in electronics will be needed to take this answer further.
Does Full Compass have audio systems for rent?
Full compass does provide audio systems for rent. They have basic amplifiers for small gatherings all the way up to professional stage quality systems.

Theory of RC coupled Amplifier?
In a two stage RC coupled amlifier the rransistor are identical and a common power supply is used. the output is provided to the first stage of the amplifier wher it is amplified and this output is uses as a input for the sexound stage this is amplified once again by the other transistor in the sexound stage and the final out put is obtain.
