Abstract
A portable digital correlator is introduced. It consists of MCU processor EP4CE6E22C8 N
USB 2. 0interface chip CY7C68013 A
high-speed optical transmitter and receiver HFBR—2526/1527
analog to digital conversion circuit
and so on. Working principle of device is described
configuration of hardware
design of software and realization of main device. Weak quantum voltage sinusoidal signal Whose peak-to-peak value is0. 8 n V is amplified correlated
data storage and calculated by digital correlator. The results show that the datatransmission speed of digital correlator is high and can be used for detection of faint signal.
