Abstract :
An analog network topology suitable for implementing continuous-time/discrete-space mixed domain rational spatiotemporal transfer functions is proposed. We also provide a generic VLSI-compatible implementation of the network based on continuous-time integrators. Numerical simulation results confirm the expected operation of a network realizing a first order velocity selective filter.
