7.1.2.2 The low-pass filter (LPF)

The low-pass filter (LPF) progressively removes high frequencies above the assigned frequency limit

(the cut-off frequency) and allows the sound below the cut-off to pass through unchanged.

Depending on the setting we will hear the sound becoming more or less «brilliant», more or less

«dampened».

This is the type of filtering that you will find most often on synthesizers that use subtractive

synthesis. It can be found on most of the recent analog and digital synthesizers.

7.1.2.3 The Resonance

A second setting to compliment the cut-off frequency: the resonance (you will also find it called

«emphasis» or «Q» – for Quality of filtering).

The resonance is able to amplify frequencies close to the cut-off frequency. Then the other

frequencies remaining are either unchanged (below the cut-off frequency) or reduced (above the

cut-off frequency). Resonance will also cause the frequencies below cut-off to be reduced, which is

one factor in the resonance sounding more pronounced. On the Jupiter 8 you can increase the

resonance through the «RES» Slider.

When you increase the resonance, the filter becomes more selective, the cut-off frequency is

amplified, and the sound can begin to «whistle» at higher settings.

The resonance amplifies frequencies close to the cut-off frequency
