The calibration filter is applied to the received radar signals in the frequency domain either before or afterpulse compression.
在脉冲压缩之前或之后，在频域向所接收的雷达信号应用校准滤波器。

Programmable hardware timing was used in design of microsecond synchronizer based on ISA bus, afterpulse generated by oscillator was divided frequency, it was sent to 8254 to count.
基于IS A总线的微秒级同步器采用可编程硬件定时，由晶振发出脉冲经分频后送入8254计数。
