Other than low-cost, his list of requirements was as follows: Dual sine wave output, synchronized Frequency, Amplitude, and Phase control Low harmonics under 1 MHz Scriptable via Python The heart ...

from a wave with zero degrees of phase shift. The t parameter, of course, is time in seconds. If you think about a sine wave, it is really showing a point on a moving and rotating circle.

a nice low-distortion sine wave with a well-controlled amplitude – Wein oscillators are a bit touchy about holding both amplitude and low distortion. From the data sheet: A1 and A2 are connected as a ...
