At a recent conference, I was given a sandwich wrap for lunch, and it was cut at an angle to display a bigger cross-section of the filling. When I unrolled it to get rid of some of the bulky tortilla, ...

So far we have mainly considered a sound wave to be a sinusoidal wave at a particular frequency. This is useful as it allows us to consider aspects of sound propagation in terms of the wavelength.

This example uses shows how two sine waves can be added to make a more complex wave form. Move the mouse cursor over the image to show the effect of changing the frequency of the second component sine ...

Analog oscillators produce excellent sine waves but are temperamental and hard to design. They also require extensive redesign every time you change the oscillation frequency. Digital oscillators are ...

How to measure linearity of an ADC using sine-wave input. How do non-idealities of a sine wave affect ADC linearity while testing it. Testing an ADC’s linearity. To obtain the transfer function of an ...

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...
