  • Angle Grinder current 18 HP oscillator state-variable-filter waveshaper

    Quadrature sine wave oscillator, state variable filter, and voltage-controlled waveshaping/distortion effect. The SPIN section outputs four phase-related sine waves (0°, 90°, 180°, 270°); the GRIND section compares each phase against an input signal and subtracts the result, producing complex waveshapes or nonlinear feedback filter outputs. All analog OTA-based design.
