SAMPLING GATES

Sampling gates are transmission circuits in which the output is the exact replica of the input during a selected time interval and is zero otherwise. the time interval for the transmission of the signal is selected by an externally impressed signal called the gating signal which is usually rectangular in wave shape. the sampling gates are also called transmission gates or selection circuits.

TYPES OF SAMPLING GATES

sampling gates may be 1. unidirectional sampling gates 2. bidirectional sampling gates

UNIDIRECTIONAL SAMPLING GATES unidirectional sampling gates are those which transmit signals of only one polarity(i.e,. either positive or negative). BIDIRECTIONAL SAMPLING GATES bidirectional sampling gates are those which transmit signals of both the polarities.
