Description:

Generates a test signal

Options:

Set to Zero: Silence is created

Set to One: Rectangle / Dirac is generated (contains all frequencies of the same amplitude and phase)

… at sample / length: determination of the delay / position of the Dirac and length (usually 1 sample)

Slope: Creates a test tone of any frequency

Use:

A neutral filter of ideal behavior can be created.

With this as a reference, subtractions or combinations of any variety can be generated.

Example:

Generating an "equal" linear comparison filter for A / B comparison
