This simple circuit has been designed to generate sine waves with a frequency of 1 KHz while featuring low distortion and low output impedance until 1 V RMS as it obtains power from batteries. Sine ...

The circuit of Figure 1 produces an accurate variable-frequency sine wave for use as a general-purpose reference signal. It includes an 8th-order elliptic, switched-capacitor lowpass filter (IC3) that ...

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 ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...
