FMout
FMout is a label used in electronics and communications to denote the output of a frequency modulation (FM) stage. The exact signal referred to by FMout varies by device and schematic, and there is no universal standard for what FMout carries. In practice, FMout can denote either the modulated RF output of an FM transmitter or the baseband audio output from an FM demodulator, depending on the context.
In FM transmitting hardware, FMout often labels the RF output of the modulator stage that feeds the
In FM receivers and demodulators, FMout commonly denotes the audio signal that results after demodulation. This
In integrated circuits and development boards, FMout may be a pin or net name representing either an
