1. This article introces the low rate of MELP speech coding algorithm and MELP voice recording device based on design. In the paper briefly described the function and pronunciation arranges encoder type, performance evaluation speech coding method based on detail, MELP speech coding algorithm is introced the outline and coding and decoding process, detailed introces how to realize the voice recording MELP based on the process of the design, the development prospect and speech coding.
2.. This paper introces the ICL7135 based on liquid crystal display (LCD) as the core, with high impedance, high precision, low energy consumption, the price is cheaper portable digital millvolts. In the measurement of power, voltage, current and frequency is the most basic of three were measured. Among them, voltage measurement is most often. But with the development of electronic technology, need more electricity measurement of voltage, so the millivolt table as a necessary measure instruments. In addition, e to the digital instrument has accurate readings, high precision, easy smaller error sensitivity and resolution measurement, high speed and etc, users, based on this table is digital millivolt demand and development.
