1. Receiver apparatus comprising:
- a digital antenna comprising a semiconductor device including a plurality of pixels, each pixel configured to produce a voltage that represents received photons at a photon frequency of the pixel;
a measurement unit configured to sample the voltage of each pixel at multiple sampling times to acquire a set of voltage samples for each pixel and to record the set of voltage samples and corresponding sampling times; and
a receiver processor configured to process the sets of voltage samples and corresponding sampling times to provide information on one or more detected signals represented by the received photons.
