1. A radio-frequency, RF, receiver circuit, for monitoring simultaneously a plurality of frequencies, the RF receiver circuit comprising:
a sub-sampler configured to:
receive an RF signal at any of the plurality of RF frequencies;
receive from a local oscillator a first oscillating signal having a first oscillator frequency; and
sub-sample, using the first oscillating signal, the received RF signal in order to generate and output an analog sub-sampled signal; and
a signal processing system coupled to an output of the sub-sampler and configured to:
receive the analog sub-sampled signal from the output of the sub-sampler;
demodulate the analog sub-sampled signal to produce a demodulated analog sub-sampled signal; and
recover from the demodulated analog sub-sampled signal a digital code that is encoded within the RF signal.
