... Ans. A vertical sync waveform is inserted in the composite video signal at the end of each field of 312.5 lines .Each vertical sync consist of (a)pre-equalizing pulses(b)field sync pulses and (c) Field Blanking Period (VB): During this period, video signal is suppressed and field retrace is complete ...
