1. A communications receiver comprising:
an input to receive a phase modulated radio frequency (RF) input signal;
a resonator coupled to the input and configured to receive the phase modulated RF input signal and to produce an electrical output signal having characteristics representative of a phase modulation of the phase modulated RF input signal, the resonator including a resistor, inductor, and capacitor (RLC) circuit, the RLC circuit having a series arm including an inductive component connected in series with a capacitive and a resistive component; and
signal processing circuitry configured to receive and process the electrical output signal to produce a decoded information signal.
