Test: Limiting & Clamping Circuits & Some Special Types of Diodes - Electrical Engineering (EE) MCQ

All of the mentioned

The output waveform is a square wave with lowest peak clamped to 0V

The output wave is a square wave with lowest peak clamped to -6V

The output waveform is a square wave with highest peak clamped to 4V

The output waveform is a straight line with the value of output voltage equal to 10V

Duty cycles can be used to describe the percent time of an active signal in an electrical device

Duty cycle can be used to determine the percentage of the time a signal is active

60% duty cycle means that the waveform is active for 40% of the total time

50% duty cycle means that the waveform is non-active for 50% of the total time

 2V_p and 0V respectively

0V and -2V_p respectively

V_p and -V_p respectively

2V_p and V_p respectively

FM transmitters

Television receivers and transmitter

Production of various signal waveforms such as trapezoidal, square or rectangular waves

All of the mentioned

It is formed by bringing metal into contact with a moderately doped n-type semiconductor material.

In the SBD, current is conducted by mainly by minority carriers.

The forward voltage drop of a conducting SBD is lower than that of a pn-junction diode.

SBD are used in the design of a special form of bipolar-transistor logic circuits
