Abstract: A digital counter receives pulses from a transducer monitoring gasoline pumped, articles moving along an assembly line, count processes in batch controlled systems, or the like. The counter stores four decades of BCD encoded data. The counter is continuously scanned and the data converted digit by digit into a serial stream of pulse width modulated bursts containing the BCD data for each digit accompanied by its associated address in the counter. The receiver operates in the reverse of the transmitter. Each incoming pulse rising edge triggers two pulse generators. If the first pulse generator times out prior to the received pulse, the received pulse will be clocked into a shift register. The second pulse generator is continuously reset during receipt of a sequence of digits. When the second pulse generator times out, the contents of the shift register is latched into a display controller. The receiver distinguishes between individual pulses and consecutive decades by the time delay between received pulses.
