These filters have a number of attributes over which we have some control. For low pass and high pass filters, we can change the cutoff frequency, allowing control of the range of frequencies affected. Running a lead synthesizer through a low pass filter and slowly moving the cutoff frequency from high to low and back is a popular technique used in electronic dance music.

Let's add an LFO to our synthesizer that causes the pitch of our oscillator to wiggle up and down a little bit, like a violinist moves their hand to create vibrato. We're also going to use the envelope generator to modulate the frequency of our filter, so we get a cool sweeping effect automatically on every note, especially if we turn up the filter's resonance. Using a control signal to change the frequency of another module is called , or , as indicated in the diagram below:

Principle of Combinatorial Chemistry

Typically, a synthesised signal generator will be used to cover the frequency range required as a series of discrete frequency steps, under the control of the test system’s software. The required frequency accuracy depends on whether the EUT exhibits any narrowband responses to interference. A manual frequency setting ability is necessary for when you want to investigate the response around particular frequencies. Be careful that no transient level changes are caused within the signal generator by range changing or frequency stepping, since these will be amplified and applied as transient fields to the EUT, possibly causing an erroneous susceptibility.
