lowest value produced by pulsefrequency
« on: March 14, 2002, 01:36:03 PM »
What is the lowest possible value that can be generated by pulsefrequency.  If it is one, and a person needs slower signal representation, I assume you would have to use a highspeed counter?

Thanks,
Ken :-/

The lowest frequency is zero. Anything with period longer than 1 second is returned as zero by "pulsefrequency(n) function.  The longest period that "pulseperiod(n)" function  can measure is 3.2 seconds.

If the signal is very slow, you can use a system clock pulse e.g. Clk:0.1s  to count the ON time and OFF time and then compute the frequency.
