A Simple Active Equivalent to a Lattice Pulse-Slimming Filter [Letter to the Editor]

In a recent article by Sierra,
¹
a symmetrical constant-resistance lattice (Fig. 1) was proposed as the realization of a passive pulse-slimming filter. A fourth-order realization contains four reactive elements in each of four lattice arms. The component values of the filter must be accurately bridged to obtain optimum results.
