Sine Wave Convertor

INTERMEDIATE PROJECT A series of projects for the not-so-experienced constructor. Although each article will describe in detail the operation, use, construction and, where relevant, the underlying theory of the project, constructors will, none the less, require an elementary understanding and knowledge of electronic engineering. Each project in the series will be based on inexpensive and commonly available components. 3b. Sine wave convertor by K. Walters The simple triangular-to-sine wave converter described here complements the basic signal source described last month. A function generator is not complete without an output that supplies a stable, sinusoidal, waveform of adjustable fre- quency and amplitude. Fortunately, a sinusoidal signal is fairly simple to generate from a triangular signal, which is supplied by the basic function gener- ator module described in last month"s instalment of the Intermediate Project series. As already mentioned there, the function generator is a ...
