Which type of signal is primarily used in analog circuits such as amplifiers and filters?

Sine wave signal

Fill in the blank: A circuit that generates sharp narrow pulses from distorted waveforms is called a __________.

Differentiator

True or False: A low-pass filter allows all frequencies above its cut-off frequency to pass.

False. A low-pass filter allows frequencies below its cut-off frequency to pass.

What is the primary function of a band-pass filter?

To allow frequencies between its higher and lower cut-off frequencies to pass.

Riddle: I can hold a waveform to a certain DC level, suppressing all excess. What am I?

Wave shaping circuit

In an astable multivibrator using a 555 timer, the output frequency depends on which two components?

Timing capacitor and resistors

Fill in the blank: The output of an inverting amplifier is given by the formula Av = -__________.

Rf/R1

True or False: Active filters do not require any external power supply.

False. Active filters require an external power supply.

Which components are exclusively used in passive filters?

Resistors, capacitors, and inductors

What does the slew rate of an operational amplifier measure?

The maximum rate at which the amplifier output can change.
