Explanation: To keep the output voltage swing within specific limit, op-amps are used with external wired components such as zeners or diodes. In the resulting circuit, the outputs are limited to predetermined values. 7. Zero crossing detectors is also called as
A. Square to sine wave generator
B. Sine to square wave generator
C. Sine to triangular wave generator
D. All of the mentioned
