Question 1:

What are the components commonly used to tune amplifiers when op amps are not suitable for high frequency requirements?

Answer 1:

LC (parallel inductor-capacitor) resonant circuits are commonly used to tune amplifiers when op amps are not suitable for high frequency requirements.

Question 2:

What happens to the impedance of a parallel resonant circuit at its resonant frequency, and how does this affect the voltage gain of a common emitter amplifier?

Answer 2:

At the resonant frequency, the impedance of a parallel resonant circuit is extremely high. When a common emitter amplifier is operated at this frequency, the collector load impedance is also at its maximum value, resulting in the maximum voltage gain of the amplifier.

Question 3:

What is the primary function of the high-pass filter, and how does it affect the amplifier’s input signal?

Answer 3:

The primary function of the high-pass filter is to filter out low frequency components from the input signal. It allows higher frequencies to pass through, improving the amplifier’s performance for certain applications.
