Abstract
PURPOSE: To output high-speed pulses of a frequency which is higher than an analog sampling cycle, by making the fetching period of analog signals and the period of output pulses independently from each other.
CONSTITUTION: A programmable timer 4 is provided with a timer II 4b, whose period is variably determined by a fixed timer I 4a which regulates the period of analog signals and inputted analog signals. Namely, the analog signals are fetched in the period regulated by a 1st timer 4a and a 2nd period is regulated by the 2nd timer 4b in accordance with the value of the analog signals whenever the analog signals are fetched. Furthermore, pulse signals are outputted from an output circuit in accordance with the 2nd period. Therefore, the output of a 2nd timer can be set to time-up frequently during the period of the 1st cycle. Accordingly, such high-speed pulse signals that numerous pulses can be outputted during a unit period can be outputted during the 1st cycle, namely, the sampling period of the analog signals.
