Workspace Method sensor_responseMixer

Description

Includes response of the mixer of a heterodyne system.

The function returns the sensor response matrix after the mixer
characteristics have been included. Frequency variables are
converted from radio frequency (RF) to intermediate frequency (IF).
The returned frequency grid covers the range [0,max_if], where
max_if is the highest IF covered by the sideband response grid.

See lo and sideband_response for details on how to specify the
mixer response
