Latest Patents

Tokyama's notable patent revolves around automatic frequency control for FM receivers. This invention presents an apparatus designed to compare the frequency of an object signal with a specified reference frequency. Integral to this patent is a reference signal generator tasked with creating a reference signal at the designated frequency. In scenarios where the object signal is frequency-modulated, the system effectively compares its center frequency to that of the reference signal. The apparatus includes a switching signal generator, switching circuitry, a frequency discriminator, low-pass filters, and a voltage comparator. The operation of the discriminator, actuated by the switching signal, alternates the discrimination between the object and reference signals. The averaged output voltages from these discriminations are compared by the voltage comparator, providing a clear indication of the frequency relationship between the two signals.
