A circuit that removes all the positive parts of the input signal is a
Show Hint
- Positive clipper
- Positive clamper
- Negative clipper
- Positive voltage doubler
The Correct Option is A
Solution and Explanation
A circuit removing positive parts is a positive clipper
- Clampers add a DC offset to a signal, shifting its baseline
- Voltage doublers are rectifier circuits that increase DC voltage
Since the circuit removes the positive portions of the signal, it is performing positive clipping
