SignalGenerator

This is a C library for generating signals :

• Sinus
• Triangle
• Ramp
• Square
• Sawtooth

Signal Parameters

Parameters	Range	Type	Sinus	Triangle	Ramp	Square	Sawtooth
Offset		F	X	X	X	X	X
Amplitude		F	X	X		X	X
Frequency		F	X	X		X	X
Sampling Frequency		Int	X	X	X	X	X
Phase	0-2π	F	X	X		X	X
Damping Factor		F	X	X		X	X
Slope		F			X
Duty Cycle	0-100	F				X

Definition :
Damping Factor : It is a coefficient to raw value of each sample like Amplitude
DF in e^(-(DT*time))

How to use

Pass 1 which one you want :

#define INCLUDE_DAMPING 1
#define USE_DOUBLE 0
#define INCLUDE_AMPLITUDE 1
#define INCLUDE_OFFSET 1
#define INCLUDE_PHASE 1
#define INCLUDE_SINLOOKUPTABLE 1

In this Library for calculating Sinus wave there are two ways:

1. using sin function in math.h
2. using an array saving 100k samples of one cycle from sinus wave

In order to use second option enable #define INCLUDE_SINLOOKUPTABLE

For each Signals two functions provided : Init and OneSample
Init functions set signal's parameters and should be called at first
OneSample functions give one sample of signal and can be called consecutively

Tests

Two tests provided [both in main.c] :

1. Generating the signals separately
2. Generating the the signals together in order to the last sample of previous signal is the offset of next signal
