Abstract
1. An electronic circuit for use with apparatus having timing signal geneing clock means and means for combining waveform information from a plurality of input channels into a single pulse train signal wherein time displacements of particular recurrent pulses along the pulse train signal time base, as established by said clock means, are indicative of the channels from which the particular pulses were derived, said electronic circuit comprising: PA1 Phase-splitter means responsive to said timing signal to provide two, timed, sine wave signals of equal magnitude but having a predetermined phase difference; PA1 Phase-shift resolver means connected to said phase-splitter means and having a stator and a rotor, said resolver being responsive to said timed sine wave signals and to the position of said rotor to provide a resolver output signal which is phase-shifted with respect to said time base in accordance with the position of said rotor; PA1 Gate shaping means connected to said phase-shift resolver means and responsive to said resolver output signal to provide a sliding gate signal which is positioned along said time base in accordance with the position of said rotor; PA1 Multiplier …
