Latest Patents
His patented invention, a scanning radio receiver, features a triple conversion superheterodyne tuning mechanism equipped with a CPU and a keyboard. This radio receiver is designed to enhance user experience by allowing programmable memory to store the frequencies received. The unique construction includes a first and second frequency mixer for frequency converting radio wave signals, which generate the first and second IF signals, respectively. A PLL frequency synthesizer within the device generates the respective local frequencies based on the desired radio wave signal input via the keyboard. Furthermore, the third frequency mixer is responsible for processing the second IF signal, which culminates in an FM demodulator and an AM detector, promising clear reproduction of FM and AM audio signals. An AM/FM switch facilitates the reception of both audio types, reverting to the instruction from the CPU for selective audio output.
