Recording process write pulse generation - uses master slave coupled flipflops with comparator output stage to convert phase encoded binary information

摘要

The phase encoding of binary information into write pulses for recording processes is provided by clocked flip-flops operating into a comparator stage. A clock generator (5) produces out of phase signals (51, 52) of the same frequency to enter input signal data (E1) into R-S flip-flops (1, 2) operating in a master-slave mode. An equivalence gate (4) generates an output when the states of the flip-flops are the same. The resulting signal is entered into an output flip-flop (3) by a third phase shifted clock signal of twice the base frequency. the output (A3) is used as a write signal.
