q signal meaning in English
q信号
Examples
- It produces the i and q signals , limits their pass bands , uses them to modulate the subcarrier in a quadrature and adds the moduled subcarrier to the luminance y , blanking and synchronizing signal waveform
它首先分离出i信号和q信号，指定了它们的传输频带，并用它们对副载波进行正交调制，然后将调制过的副载波信号叠加到亮度信号y和同步信号波形上。 - Ts signal input interface into the data buffer . after finishing the data buffer parameters set by synchronous data output signal . on the dvb standard with the base - band formed after channel i , q signals . by the square root of roll - off filter for qam modulation , frequency modulation by the panel set up , qam have had to deal with the final if if interface circuit sent to the rf channel
Ts流数据信号经输入接口送入缓存器，缓存器对数据进行整理后按设置参数输出同步数据信号，经符合dvb标准的各种信道处理后形成基带i q信号，经平方根滚降滤波进行qam调制，调制频率由面板设置，已调qam信号最后经中频if接口电路处理送至射频通道。
