信号延迟发生在许多系统中。在卫星通信和多卜勒雷达系统中,由于发射机和接收机间长距离的信号传输,可观的时延影响到系统的正常工作,延迟信号的数学表达式是很需要的,以便分析延迟线对系统响应的影响。延迟绂的这些表达式应用于解调电路、鉴频电路、相位噪声测量系统和多卜勒雷达系统中。 Signal delay occurs in many systems. In satellite communications and Doppler radar systems, due to the long delays in signal transmission between the transmitter and the receiver, appreciable delays affect the normal operation of the system and a mathematical expression of the delayed signal is needed in order to analyze the delay line Impact on system response. These expressions for delay 应 are applied to the demodulation circuit, the discriminator circuit, the phase noise measurement system and the Doppler radar system.
