The digital timer has the characteristics of clear and clear display. It decodes the digital pulse signal representing time through a digital device and then displays it on a digital display tube. This circuit introduces a digital display timer with a one-digit display, and its display unit is determined according to the unit of the time base signal. It can be "seconds", "minutes", or of course "hours". However, for a digital one-bit timer, the unit of "hour" is too large. Due to the structure of the circuit, it is not easy to achieve accuracy, so it is rarely used. Its circuit composition is shown in the figure. This circuit is composed of time base signal generator , time counter, digital decoder and digital display.
