This function provides an ARMA spectral estimate which is maximum entropy satisfying correlation constraint (number of poles)and cepstrum constrains (number of ceros) The function requires 3 inputs: Input signal, Order of denonominator, Order

Inputs digital data into a buffer from a group of two digital ports using hanshaking (for 8255-based devices).

This program demonstrates how to configure the port pins as digital inputs and outputs. The C8051F320 target board has two push-button switches connected to port pins and and two LEDs. The program constantly checks the status of the switches

Compute the output of a general delta-sigma modulator with input u, a structure described by ABCD, an initial state x0 (default zero) and a quantizer with a number of levels specified by nlev. Multiple quantizers are implied by making nlev
