Sine squared shaping of sync and drive pulses

Networks for generating or shaping sine-squared synchronizing pulses utilized in television systems are discussed and the reasons for their use are explained. Some tests of a simple shaping network which demonstrate the usefulness of sine-squared shaping are described. The network considered utilizes a delay line, or clocked shift register to allow generation of multiple delay versions of the sync pulse, with weighted summing of the delayed signals to produce the desired shaping.<
