Parameter: Filter cutoff freq.

Full name: Cutoff frequency of filter
Units: Hz
Range: [ 0 Hz, 1000000 Hz ]
Initial value: 0 Hz

Affects: Filter operation

Set this parameter to the cutoff frequency of the digital filter. The program limits the cutoff frequency to 1/3 of the sampling rate of the waveform, to avoid the "ringing" caused by too high a cutoff frequency.

If set to zero, the actual filter will be disabled, but the other processing performed by the "Filter" operation will still occur. This is useful if you want to clip or rectify a waveform without actually filtering it.
