SignalGenerator

This module implements a simple ROM-based Signal Generator Module with PWM. Selector allows to switch to several signal types:

Sine
Triangle
Sawtooth
Square

Architecture Overview

Usage

User specifies the signal waveform accuracy (depth & size of ROM) in bits, the expected frequency output and a frequence error range in Hz.
