Abstract

PURPOSE:To make it possible to obtain needed transfer characteristics freely and to realize IC-implementation easily, by digitizing a phase synchronous loop. CONSTITUTION:Input signal fi inputted to terminal 1 is converted into pulse Pi by polarity inverter 11. Now, when the PLL composed of phase comparator 12, counter 13, variable divider 14, and reference-pulse output circuit 16 is in a synchronous state, variable dividier 14 divides clock pulse CP inputted from input terminal 15 by N and outputs reference signal f0 synchronizing with Pi. Next, once Pi leads (or lags) reference pulse P0, phase comparator 14 outputs leading (or lagging) phase pulse Pa (or Pb). Phaseadvancing counter 13a (or 13b) outputs leading (or lagging) phase control signal Ea (or Eb) when its count number overflows. Variable divider 14 changes the division number of the CP from N to N+1(N-1) by Ea (or Eb) to advance (or delay) the phase of f0.
