Latest Patents

Noboru Usami holds a patent for a "Multi-channel frequency converter having automatic control." This device is designed to frequency-convert multi-channel broadcast signals. It consists of a local oscillator that generates a single oscillation frequency at a time, a mixer, and a frequency discriminator. The frequency discriminator automatically controls the oscillation frequency of the local oscillator. It delivers a DC zero voltage when the frequencies of multiple signals coincide with those of the carrier waves. Conversely, if the frequencies differ, the discriminator provides a DC output voltage whose amplitude reflects the difference.
