In this minimalistic square wave generator circuit, the RC network is composed of a 4.7KΩ resistor and a 100nF capacitor. So, we obtain a frequency of approximately 1.5kHz. Since the output square ...

Figure 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency. Figure 1 Just a couple of components are needed for a simple ...

In this article, we'll review the most common methods for the computing and generating a sine wave on a programmable DSP, as well as provide a brief introduction to direct digital frequency synthesis ...
