DSP Trick: Sinusoidal Tone Generator
Subject: Trick : Tone Generation From: Darrell <darrell@havoc.gtf.org> Date: 1999/04/19 Newsgroups: comp.dsp THIS WORK IS PLACED IN THE PUBLIC DOMAIN
Name: Sinusoidal tone generator
Category: Algorithm
Application: If they need to generate a continuous tone of specific frequency and amplitude.
Advantages: Fast and accurate.
Introduction:
I've seen this trick in a few different places, although never the (very simple) deriviation.
How to Create Oscillators in Software
How to Create Oscillators in Software
by Matt Donadio
Oscillators can be created in software directly, using the "sine" function, or they can be calculated indirectly using several different iterative methods. We survey those methods here.
Notation:
First, let's assume that:
