Signal Generator

A sine wave, sinusoidal wave, or just sinusoid is a mathematical curve defined in terms of the sine trigonometric function, of which it is the graph. It is a type of continuous wave and also a smooth periodic function. It occurs often in mathematics, as well as in physics, engineering, signal processing and many other fields.

Basically, the reduced form of a wave takes the form

$$y(t) = A sin (\omega t + \phi)$$

at where

• A is the amplitude,
• omega the angular frequency
• phi the phase

Given the three parameters and a time delay ($ \delta t$) return an Iterator that can produces the signal plotted in intervals of $ \delta t$ truncate to 2 decimals

For example:

• A = 3 m
• $ \omega $ = 2 rad/seg
• $\phi$ = 0 rad
• $\delta t$ = 0.1 s

produces

• i = 0 -> y(0.1) = 3* sin(2*0.1) = 0.59
• i = 1 -> y(0.2) = 3* sin(2*0.2) = 1.16
• i = 2 -> y(0.3) = 3* sin(2*0.3) = 1.69

Note:

• The iterator must be unbounded.
• Time interval must be positive.
