Voltage Controlled Filter SSM2044P

At this circuit the SSM2044 IC is used, a 4 pole voltage controlled filter designed for electronic music applications. On-chip voltage control of resonance allows direct and easy interfacing with programmers and controllers. The IC features extended control range, low noise, and high control rejection. The filter can also be used as a low distortion sinewave oscillator.

Gates provide low-cost sine-wave generator

One of the troubleshooting tests required for telephone/data twisted-pair copper lines is the determination of the attenuation factor. The test uses frequencies of 300 to 4000 Hz to plot the attenuation performance. Because many central-distribution lines are in locations where power lines are unavailable, a battery-powered generator is desirable for the testing. The circuit in Figure 1 runs from 6 to 9V dry-cell batteries. …

synthesizer generates 19-kHz pilot tone for FM baseband signal

This Design Idea presents a low-cost method of generating the basic 19-kHz pilot tone. The 19-kHz pilot tone comprises a baseband signal, and the L+R and Lâ€“R signals consist of DSBSC (double-sideband-suppressed-carrier) modulation centered at 38 kHz. For a receiver to correctly demodulate the signal, the transmitted pilot tone and Lâ€“R signal must synchronize at their respective zero crossings. …
