ABSTRACT:
An analog real-time signal processing device and method are presented. The device is configured to perform electrical signal processing. The device comprises an electronic circuit including at least one basic unit of electrodes, the basic unit being configured to be sensitive to an external field, such as input photon flux, indicative of a first input signal to cause emission of charged particles and configured to define at least one electrical input for a second input signal and one electrical output, thereby providing the electrical output in the form of an approximation of a product of the first and second input signals.
