Exam 20: Nonlinear Op-Amp Circuit Applications Key

Monolithic op amps are inexpensive,versatile,and reliable.

A circuit that performs a mathematical operation and produces a ramp of output voltage is known as

A comparator that uses positive feedback is called a Schmitt trigger.

A comparator is sometimes called a limit detector because a positive output indicates that the input voltage exceeds a specific limit.

What is the output waveform of a zero-crossing detector when the input signal is any periodic signal that crosses zero threshold?

The duty cycle is equal to the

A circuit that generates an output signal whose frequency depends on the charging of a capacitor is the

A double-ended limit detector detects when the input voltage is between two limits called the window.

An integrator circuit produces amplified sine waves at its output.

A differentiator can be configured by using
