Filter designer


This flexible digital filter allows filtering the input signal of the analyzer. In addition you can also integrate this filter to the signal generator.

For example you can remove any signals below 100Hz and focus to the range from 100Hz to 3000Hz. All other frequencies are removed and not considered for calculation.

You can freely define both the low and high cut frequency.

With the ability of the signal generator to play .wav files you can also filter these .wav files while playback.

This feature is widely used to generate narrow-band noise.
