Convert RF signal to baseband signal

**Library:**RF Blockset / Circuit Envelope / Systems

The `IQ Demodulator`

converts an RF signal
to baseband signal. `I`

stands for the in-phase component
of the signal and `Q`

stands for the quadrature phase
component of the signal. You can use the IQ Demodulator to
design direct conversion receivers.
