Title: Yasumoto Murata: Innovator in Signal Processing and Voice Technology
Introduction
Yasumoto Murata is a distinguished inventor based in Nara-ken, Japan. He has made significant contributions to the fields of signal processing and voice technology, holding a total of 13 patents. His innovative work has paved the way for advancements in various electronic devices.
Latest Patents
One of Murata's latest patents is a signal discrimination circuit. This circuit is designed to determine whether an input signal contains a control signal, which has a specific frequency and level for a defined duration. The circuit includes a component power detection device that detects the power of a component within the input signal, as well as a level judging device that assesses whether the power meets a reference value. Additionally, a control signal judging device confirms the presence of the control signal based on the power assessment over a specified time.
Another notable invention is a stereophonic voice recording and playback device. This device is capable of stereophonically recording and reproducing voice signals. It features an adding circuit that receives two channel analog voice signals, performs orthogonal conversion, and combines the signals. An Analog-to-Digital (A/D) converter then transforms the added signal into a digital format, which is subsequently compressed and stored in a memory circuit. Finally, an expanding circuit retrieves the digital signal from memory to reproduce a stereophonic output.
