Sampling Clock Generator for Discrete Filters

The Sampling Clock Generator for Discrete Filters generates the narrow pulse width TRIG signals for use with the discrete time filters. You can think of this device as a one-shot which triggers on every rising edge of the input clock. The output pulse is set by the Acquisition Time parameter.

Subcircuit Parameters

Because this sampling clock generator for discrete filters model is generated by a template script when the simulation is executed, a fixed model cannot be inserted into a netlist. The template script for this device is simplis_make_digital_filter_model.sxscr, which you, as a licensed user, can download in a zip archive of all built-in scripts.
