digital sine-wave oscillator

7-38 — elektor July/august 1981 37 digital sinewave oscillator An assortment of digital sinewave generator circuits have found their way into the pages of Elektor magazine over the years, as in last year"s Summer Circuits issue for instance. However, the circuit de- scribed here requires fewer components than usual and therefore produces a sinewave signal that is perhaps not quite so good qualitywise, but never input of N1 will go high via R1 and the whole procedure will be reversed. Readers interested in this type of oscillator are referred to the National Semiconductor Application Note No. AN-118, which is included in their current CMOS data book. The divide-by-three section consists of two flipflops which both divide by two, in other words, it would be expected that together they would divide by less serves its purpose very well. fin tin 3 The circuit consists of two sections, each of which s own: an could have many useful applications nit oscillator constructed around a pair...
