摘要： An analog-to-digital converter comprises an output generator for forming an output signal in response to application of a start signal; a comparator for comparing an analog signal, to be converted to a digital signal, with the level of the output signal formed by the output generator and for providing an output representing the time period from initiation of formation of the output signal to occurrence of a predetermined relation between the output signal and the analog signal; and a clock signal generator. The converter further comprises a digital computer that includes an output terminal from which the start signal is applied to the output generator and an input terminal for receiving the output from the comparator. The computer further includes a counter for counting the pulses produced by the clock signal generator from the time the start signal is applied from the output terminal until a time when the input terminal receives the output representing the aforesaid time period, and a digital signal generator for forming a digital signal corresponding to the output signal on the basis of the count of clock pulses by the counter.
