### Purpose

Convolution of two signals

### Description

"Convolution" creates a new signal z by performing the convolution
of two signals x and y defined by

Internally, a frequency-domain algorithm based on the Fast Fourier Transform is used for calculating the discrete convolution.
**Warning:** *Note that if the input signals have different x-axis scales (sampling periods), the signal with the largest scale will be adapted automatically by interpolating between successive sample points. The type of interpolation can be set in the Basic Options menu.*
