First-order derivatives: n additional function calls are needed. Second-order derivatives based on gradient calls, when the "grd" module is specified (Dennis and Schnabel 1983): n additional gradient ...
Abstract: This paper presents a four-level pulse amplitude modulation (PAM-4) receiver employing a time-based finite impulse response (FIR) and infinite impulse response (IIR) decision feedback ...
Prismo implements the Finite-Difference Time-Domain method for solving Maxwell's equations, with features designed for photonic integrated circuits, waveguides, and optical devices.
