Latest Patents

Li-Cheng Hsu holds a patent for a "Signal demodulating method of a two-phase frequency shift keying (FSK) digital demodulator." This method involves a signal demodulating technique that utilizes a detect circuit to collect both positive and negative edge signals of an intermediate frequency signal. By employing two n-bit ripple counters, the method refers to a threshold value and uses the edge signals as switch signals to reset the threshold value. This process initiates counting and comparison to output both positive and negative edge data bits. Ultimately, a hard decision logic circuit performs a frequency-descending decision based on these data bits, resulting in a base frequency signal. This innovative approach reduces the number of logic gates required, shortens signal delay time, and enhances the resolution of demodulation. The method aligns well with the compact trends in wireless products.
