Gated Pulse Frequency generator (80)

image-1703199575965.pngGated Pulse Circuit (80) of Figure (3-5) switches "off' and "on" sections of incoming clock signal (42) to form gated pulse (45) which is, in turn, duplicated in succession to produce gated pulse train (46a xxx 46n) of Figure (3-17).

Together pulse train (44a xxx 44n) and pulse off-time (43) forms gated pulse duty cycle (45).


Pulse train (44a xxx 44n) is exactly the same as pulse train (41a xxx 41n) and its established pulse frequency (number of pulse cycles per unit of time) changes uniformly when pulse generator (70) of Figure (3-5) is calibrated and adjusted for system operations.

Newly formed gated duty pulse (45) is proportional to the physical change in pulse train (44a xxx 44n) when circuit (80) is adjusted for calibration purposes.

Pulse train (44a xxx 44n) becomes widened while pulse off-time width (43) becomes smaller, simultaneously.

Conversely, opposite pulse shaping occurs when circuit (80) of Figure (3-5) is calibrated in reverse order.
