CLOCK_FOR_COMMUTATING_RC_FILTER
Circuit synchronizes multivibrator with line frequency to provide dock waveform required for switching capacitors electronically in npath active filter for rejecting line frequency and harmonics up to fifth. Article gives complete circuit of active filter and describes operation. Clock serves to switch 16 MOSFETs on in turn for commutating 16 capacitors electronically at 16 times line frequency.-K. F. Knott and L. Unsworth, Mains Rejection Tracking Filter, Wireless World, Oct. 1974, p 375-379.
