  2. PRI VPeak TC PRF: Definition • Pulse repetition frequency (PRF): Number of pulses occurring in 1 s. • Pulse repetition interval (PRI): Time from the beginning of one pulse to the beginning of the next. Francois Chin (I2R)

  3. PRF Definition : Example Pulse Repetition Interval 1 2 3 4 5 6 7 8 N-1 N ………………………… Non-inverted pulses are blue, Inverted pulses are green. Pulse Width, Tc ~ 4ns @ 500MHz BW ………………………................. …………… Quiet time Active time Symbol Interval Francois Chin (I2R)
