Implementing sine, square, triangle and Sawtooth Waveforms.
|Updated||Jan 01, 2016 (5 years ago)|
Draw Waveforms is a basic app for drawing limited scale signal graphs on your device. You can set the values of amplitude, frequency, time interval and phase.
Here some wikipedia info:
The sine wave or sinusoid is a mathematical curve that describes a smooth repetitive oscillation. It is named after the function sine, of which it is the graph. It occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields. Its most basic form as a function of time (t) is:
y(t) = A . sin( 2 . π . f . t + Φ )
A square wave is a non-sinusoidal periodic waveform (which can be represented as an infinite summation of sinusoidal waves), in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum.
A triangle wave is a non-sinusoidal waveform named for its triangular shape. It is a periodic, piecewise linear, continuous real function.
The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a saw.
Attention: Trying big decimal numbers to plot the graph may cause crash, please try only acceptable values by a mobile phone. By installing the app you will take all the responsibility.
