| Abstract: | A new high speed single pulse selector is designed based on DSP. The design method, operation principle, parameter set and analysis of characteristic curve are introduced. This new device is composed by DSP, intensity modulator, intensity modulator drive circuit, high speed amplifier, AGC circuit, light detect and amplify circuit, the circuit of pulse detect and reserve, and so on. Controlled by a controlling signal, the module can select single pulse from the pulses range. It also has a high extinction rate （≥30dB） and low insertion loss（≤7dB）. |
| Keywords: | DSP processor single pulse selector intensity modulator extinction rate insert loss pulse detect and reserve |
