In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of ...

Instead, many manufacturers provide ready-made voltage-controlled oscillator (VCO) ICs that need only a few ... The table that accompanies the schematic diagram provides rough indications of component ...

The required input or control voltage to the VCO is generally higher ... Figure 1 shows a block diagram of a PLL-based frequency synthesizer. The VCO generates the output signal.
