What is the operation of a antilogarithmic amplifier?
An antilogarithmic amplifier, or antilog amplifier, is a type of electronic circuit that performs the inverse operation of a logarithmic amplifier. It takes a logarithmic input signal and produces an output that is proportional to the exponent of that input. This is typically achieved using a transistor or operational amplifier configured to respond to the input voltage in a way that generates an output current or voltage exponential to the input. These amplifiers are commonly used in applications requiring signal processing in fields like telecommunications and instrumentation.
How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
What does a jack do in an amplifier circuit?
A jack is a connector socket designed for the insertion of a plug. The plug can connect input, output, or auxiliary devices to the amplifier circuit.
How op-amp can be used as adder?
An operational amplifier (op-amp) can be configured as an adder using a summing amplifier circuit. In this configuration, multiple input voltages are fed into the inverting terminal through resistors. The op-amp produces an output voltage that is proportional to the negative sum of the input voltages, scaled by the resistor values. By using feedback and appropriate resistor ratios, the circuit can be designed to add the input voltages with desired gain or weighting.
What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.

Why a high input impedance?
A circuit (an amplifier) typically has a high input impedance so that it does not unduly load the input circuit. Any such load could cause distortion, and that is generally not desired.
What is buffer amplifier and its applications?
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
What are the applications of fixed bias amplifier circuit?
low input impedance

What does the OP stand for in OP amps?
Op amps stands for operational amplifier. An operational amplifiers is a high gain voltage amplifier that requires a differential input and produces single outputs.
What does a comparator do in electronics?
A comparator is an operational amplifier used without a feedback circuit. The output of the comparator will be high when the voltage of the non-inverting input is below the inverting input, and low when the inverting is above the non-inverting input. The output is undefined - i.e. can by anything - when the voltages are equal.
Circuit diagram of RC coupled amplifier?
One of the several uses of an RC coupled amplifier is to amplify the given input signal. It makes use of a sinusoidal input signal.
