Mark IV多用途话音码编器由美国GTE Sylvania公司研制的Mark IV型话音编码器是一台结构紧凑的机架式或台式的独立语言编码器。采用予测编码和付里叶变换数字语言处理技术对模拟语言进行数字化与合成,并提供1.2—16千比特/秒的数据速率。该数码终端的主要特点是:具有保密话终端的能力;在语言处理设计上采用了微处理器技术;在单个设备中还能提供完整的加密能力;它的语言编码结构形式包
Mark IV multi-purpose voice coder developed by the United States GTE Sylvania Mark IV-type voice encoder is a compact rack or desktop independent language encoder. The predictive coding and Fourier transform digital speech processing techniques are used to digitize and synthesize analog languages and provide data rates of 1.2-16 kbit / s. The main features of the digital terminal are: the ability to have a secret terminal; microprocessor technology is used in the language processing design; complete encryption capability is provided in a single device; its language encoding structure package
