Abstract:
A circuit for producing an electrical signal which is a replication of a mathematical model which can include ac and/or dc bipolar waveforms comprising:a modulator wherein an output sequence of zeros and ones produced by said modulator represents said mathematical model;a digital code generator connected to receive said output sequence from said modulator wherein an output digital code signal is produced to represent said mathematical model;a sinusoidal frequency generator whose output drive frequency is synchronized to said digital code;a Josephson quantizer connected to be driven by said digital code generator and said frequency generator wherein the quantized bipolar output pulses of said Josephson quantizer represent said mathematical model; andan analog low pass filter connected to receive said quantized bipolar output pulses and produce an output signal which is a replication of said mathematical model including models of ac and dc bipolar waveforms.
