High quality television display screen used to view a TV signal in its unmodulated state. ( Modulate-to vary the amplitude, frequency or phase of radio or television). 用于收看未经压缩的电视信号的高质量屏幕,以监控图像质量。
The unmodulated carrier first transmits at the center of the mask, and the top of the mask adjusts to correspond with the output power of the transmitter. 未调制载波首先传送到遮罩中心和顶部,与相应发射机的输出功率相适应。
A method of frequency stabilization& bias frequency locking, for output of unmodulated laser is introduced. 本文介绍了一种无调制激光输出的偏频锁定稳频方法。
An unmodulated stable laser system, which has been used as a tunable CO_2 laser sideband coherent source, is introduced. 本文介绍用于可调谐CO2激光边带相干光源的稳频激光系统。
The IRIG-B code is essentially a modulating code for width of pulse with the unmodulated signal being 100 bits of 2-ms code per second, and its information bits are expressed as the width of pulse. 从本质上看IRIG-B码的码流结构是一种脉宽调制码,其未经调制的信号为每秒100个2ms的码元,信息位是由固定位的脉冲宽度表示的。
