Abstract
The equipment is composed of surface acoustic wave filter in RF, amplifier in low noise, mixer, amplifier in MF, surface acoustic wave filter in MF, logarithm detector amplifier, and comparator in sequential series connection of co phasal input ends. Simulating method is as following: through surface acoustic wave filter in RF, inputted carrier signal magnified by amplifier in low noise; then signal passes mixing so as to obtain MF carrier signal; passing through magnification in MF, and MF filtering, MF carrier signal enters into logarithm detector amplifier to carry out demodulation; being transmitted in mode of time slot frame structure, analog signal passing through demodulating by logarithm detector amplifier generates envelope signal in LF; through comparator, envelope signal in LF generates pulses in LF, which is sent to a single chip for counting; and number of pulse in a frame structure is accumulated.
