lowest value produced by pulsefrequency

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.
