Latest Patents
Hiroshi Yuguchi holds a patent for a method titled "Frequency band compression of FDM using time expansion." This invention focuses on a frequency band compression technique that utilizes time compression for frequency division multiplex (FDM) signals carrying voice signals. The method involves dividing the multiplexed signal into multiple time segments, deleting parts of each segment, and time-expanding the remaining portions using a sawtooth variable delay. This process effectively lowers the frequency of the signal to a predetermined ratio. On the receiving end, the signal segments are compressed by a corresponding variable delay, allowing for the reproduction of the original multiplexed voice signals.
