摘要:
A pulse circuit to solve a system of differential equations in the pulse domain based on analog or inputs or time-encoded pulse inputs. Intrinsically linear 1-bit digital to analog converters are used as feedback elements within circuits implementing solutions to a differential equation or to a system of differential equations. The circuits may be used to implement filters. While the input to the circuit may be an analog signal, the internal signals of the circuit are time-encoded current or voltage pulses. Output of the circuit is a time-encoded pulse or a series of time-encoded pulses from which an analog output may be recovered by time decoding.
