Gated Pulse Frequency generator (80)

Gated 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 offtime (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
 widen 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.
