  • Voltage-controlled phase shifter circuit for an electronic musical instrument
    Patent number: 4122364
    Abstract: A phase shifter circuit in electronic musical instruments, in which sound effects are generated by varying the amount of phase shift through voltage control. The amount of a shift may be linearly varied by an external voltage, and the operating point of the phase modulation can be freely set over a substantially wide range. The amount of phase shift, furthermore, may be made large so that a circuit stage having a pair of transistors is designated as a unit, and several such units are cascode-connected. Adjustment of this unit is not required.
