Abstract The digital method of realizing high speed random modulation includes the following steps: inputting required parameters via computer and feeding them into programmable logic controller; generating random code in random code generator and feeding into the programmable logic controller; delaying the random code in the programmable logic controller, reading out data through table check-up according to the input parameters and feeding the data into D/A converter; converting the digital amount in the D/A converter into output analog waveform. Realizing in digital chip can raise the controllability and reliability of system and lower hardware cost.
