TI Hercules LaunchPad Tipo 2: Electromyography Signal DSP part 2

 

Improvements myoelectric sensor circuit is performed.

 

improvements:

 

- No Bandstop filter 60Hz / 50Hz is used

- The bandpass filter is 300Hz to 3KHz

- Filtering is entirely digitally Fourier

- The MCU digital filtering helps in reducing the circuit

Amplifiers - MCP6022 / Microchip, do not use a single integrated circuit as an amplifier for reasons of flexibility in design.

    yes, I add a delay in program for the reason that you can see the change of the numbers on the LCD while I record the video for youtube.

     

    the time spent for get the signals with ADC, calculation Fourier and digital filtering signals for the arm right and left is in milliseconds, is very fast,

    couldn't see in the video!
