术语	pulse code modulation (PCM)
释义	pulse code modulation (PCM) 脉(冲)码调制(技术,法);［脉码调变］ 1. A technique for converting analog information into digital form. The analog signal is sampled at a rate equal to at least twice the maximum signal frequency component, and the sampled value is represented by a fixed length binary number. This number is then transmitted as a corresponding set of pulses. 把模拟信息转换成数字形式的一种技术,用大于等于两倍的最高信号频率的速率对模拟信号进行采样,并用一个定长的二进制数来表示这个采样值。这个数以一组相应的脉冲来传送。 2. A process in which a signal is sampled,and the magnitude of each sample with respect to a fixed reference is quantized and converted by coding to a digital signal. 一种处理方法,其中对信号进行采样,把每个采样点相对于一个固定的参考基准的幅度加以量化, 然后通过编码变换为数字信号。 3. The sampling and quantization of signals in the transmission of analog data. The value of the quantized sample is transmitted as a distinct pattern of pulses, i.e., the value can be expressed as a binary number and transmitted as a sequence of pulses representing 1s and spaces representing 0s. 在模拟数据的发送中,信号的取样和量化,这种量化取样的值用不同模式的脉冲发送,也就是说, 此值用一个二进制数表示并用一系列脉冲(表示1)和空号(表示0)发送。
