The shape of externally applied or an impressed control signal in a sampling gate is usually _____.

Options:

a. square
b. rectangular
c. diagonal
d. elliptical

Correct Answer:b. rectangular

Explanation:

Basically, the sampling gate is a transmission circuit where the output is an exact reproductivity of an input waveform within a specified time interval and can also be zero otherwise.

The time interval for the transmission purpose is adopted with the support of an external signal called as control signal or gating signal.These control signals are usually defined in terms of rectangular shape.

However, sampling gates are most oftenly renowned as 'Transmission Gates' or 'Time Selection Circuits'.
