Red FM 93.5 Interview Questions and Answers

Use a flip-flop to divide the frequency by 2.

• Use a D flip-flop with the input connected to the clock signal and the output connected back to the D input.

• The output frequency will be half of the input frequency (25MHz).

Op amp stands for operational amplifier, used in various electronic circuits for amplification, filtering, signal conditioning, etc.

• Op amp is a high-gain electronic voltage amplifier with differential inputs and single output.

• It is commonly used in audio amplifiers, signal conditioning circuits, filters, oscillators, etc.

• Op amps can be used in instrumentation amplifiers, voltage followers, integrators, differentiators, etc.

• Examples of op amp ICs include LM741, LM358, AD822, e...read more

Clipper with the help of opamp is a technique used to limit the output voltage of a signal.

• Clipper circuit is used to limit the voltage level of a signal by clipping off the peaks.

• Opamp (operational amplifier) is a high-gain electronic amplifier used to amplify and manipulate signals.

• By combining a clipper circuit with an opamp, the opamp can be used to control the clipping level and shape the output signal.

• The opamp can be configured in different ways, such as inverting or n...read more

A clipper circuit is an electronic circuit that limits or clips the voltage level of a waveform.

• There are two types of clipper circuits: positive clipper and negative clipper.

• Positive clipper circuit limits the positive half of the input waveform.

• Negative clipper circuit limits the negative half of the input waveform.

• Diodes are commonly used in clipper circuits to perform the clipping operation.

• Examples of clipper circuits include series clipper, shunt clipper, and biased cli...read more

A clamper circuit is used to shift the DC level of a signal without changing its shape.

• Positive Clamper: shifts the DC level of the input signal to a higher level

• Negative Clamper: shifts the DC level of the input signal to a lower level

• Biased Clamper: shifts the DC level of the input signal to a desired level using a biasing voltage

• Diode Clamper: uses diodes to clamp the input signal to a specific DC level
