    <div class="sphx-glr-thumbcontainer" tooltip="Sinusoidal waves are very useful in signal generation. The sine wave equation can be used to generate a simple wave (wave 1 in the top left panel) or complex signals in a few steps. The figure below shows the generation of four different waves that are recursively added together to create an increasingly complex signal. And, combining it with other signals, such as sloping line, increases its functionality. The bottom panel of the figure shows all the waves plus a linearly increasing signal.">
