The output is switched on and off depending on two frequencies which can be specified.
The threshold trigger measures the signals at input Fre. The pulses are captured across a measuring interval which can be specified. If the frequency measured within the measuring interval higher than the input frequency, the output Q is switched to Hi
. Q is switched again to Lo
when the measured frequency has reached the value of the output frequency or if it is lower.
