Abstract

PURPOSE:To enable to output the signal such as set frequencies, with a simple constitution, by performing setting with the carry or borrow output of the first count er by FF, resetting it with the output of them of the second counter, and outputting the output as the pulse signal. CONSTITUTION:The first counter 2 counts the clock pulse in specified frequency, and presets the frequency information from the frequency information setter 6 with the carry or borrow output, and the second counter 3 counts the clock pulse and presets the pulse width information from the setter 7 with the carry or borrow output of the counter 2. Further, FF8 is set with the carry or borrow output of the counter 2 and is reset with the carry or borrow output of the counter 3, and the output is outputted as the pulse signal based on the frequency information, pulse width information and frequency of the clock pulse. Thus, with a simple constitution, the pulse signal having the frequency and pulse width based on arbitrary frequency information and pulse width information can be developed.
