What is DC coupled amplifier?
A: DC couple amplifiers refers to stages of amplifiers where is the biasing is direct without adding capacitors to remove the DC component from amplifier to amplifier
What is the circuit diagram of a sense amplifier?
sensing amplifiers and its circuit diagram
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
What is meant by the term large signal amplifier?
power amplifiers are the amplifier which raise the power levels of the signal.the power amplifier may also defined as a device which converts dc power to ac power and whose action is controlled by the ac input signal. Power amplifiers are also known as "LARGE SIGNAL AMPLIFIER".the term large signal arises because they use large part of load line for their operation,but the small signal amplifiers are use only 10% load line for their operation.
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 are the two types of rf amplifiers?
A unidirectional amplifier & a Bidirectional amplifier
What is DC coupled amplifier?
A: DC couple amplifiers refers to stages of amplifiers where is the biasing is direct without adding capacitors to remove the DC component from amplifier to amplifier
When diode is used as an amplifier it is operated in what?
Diodes are not amplifiers.
What is advantage and disadvantages of multistage amplifier?
A multistage amplifier is composed of several single stage amplifiers.
What's the amplifier "classes" ?
Amplifiers can be binned into basic, prosumer, and professional amplifiers, with a corresponding increase in cost.
What does balanced amplifier consist of?
Two amplifiers stuck together.
What are the applications of class a power amplifier?
low power linear amplifiers
Where is the amplifier in a 2003 Lincoln Navigator?
Where is the amplifiers in a 03 Lincoln navigator
What is the circuit diagram of a sense amplifier?

Why amplifier is required?
Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
Where can one purchase an NAD amplifier?
NAD amplifiers appear to be sold online by Crutchfield or Amazon. One could find NAD amplifiers by searching "NAD amplifier". Alternatively you could navigate to the Crutchfield or Amazon websites and search for "NAD Amplifier" direct from those websites.
