How to Generate a Basic Sinusoid
Find out how to construct a simple sinusoid.
We'll cover the following
Mastering the DSP toolkit starts with a basic sinusoidal signal.
A sinusoid
As a function of time , a real sinusoid is given by:
There are three parameters that determine the actual signal:
- Amplitude
- Frequency in cycles/sec or in radians/sec, and the time period is or
- Phase
It’s a convention to use a cosine wave because we know that a sine wave is also a cosine wave with a specific phase.
A really basic sinusoid with , and is shown below:
