11.5.8 Discrete Time Mixer
The discrete time mixer is used for modulating (shifting signals in frequency down) where the output frequency of the mixer is equal
to the difference of the input frequency and the local oscillator frequency. The discrete time mixer is created using a SC/CT Analog
Block, see the Mixer component data sheet in PSoC Creator for full AC/DC specifications, and APIs and example code.
