Abstract : The timer generates a selected number of control pulses per hour, at unpredictable (pseudo-random) intervals, for use with a time lapse video tape recorder user for time studies. The hour is divided into equal intervals to provide the number of samples required per hour, and one trigger pulse is generated randomly timed within each interval. A noise generator drives a counter whose outputs are loaded with every Nth clock pulse into an N-stage shift register. The contents of the shift register are shifted out serially at the clock frequency. (Author)
