Latest Patents

Chun-Sub Kim holds a patent for a sine-wave modulator and playback/recording modulator-demodulator. This innovative device features a voltage-controlled oscillator (VCO), a voltage-current inverter (VCI), a band-pass filter, an amplitude limiter, and a phase-locked loop. In playback mode, the device processes the playback input signal through the band-pass filter, activating the phase-locked loop. The VCI generates a reference signal that tunes the playback input signal, leading to a demodulated playback output. In record mode, the VCO produces a frequency-varying signal based on the record input voltage, allowing for controlled bandwidth in the band-pass filter. This dual functionality enhances the versatility of the device in both playback and recording scenarios.
