RF receiver circuit is a follow-up processing circuit of
dynamic torque sensor. It mainly completes the task of
signal-receiving, processing, displaying and printing etc.
Digital signals received by RF receiver chip need to be
isolated and filtered to eliminate interference. Then they
enter a MCU (Micro Control Unit) for computing and are
converted into the corresponding torque value. MCU can
be connected with keyboard, monitor, printer and RS-232
serial port, and can also be connected with a computer
through the serial port. System scheme block diagram is
shown as Fig. 2.
