A DESIGN OF DSPIC BASED SIGNAL MONITORING AND PROCESSING SYSTEM

Journal Name:

Publication Year:

Abstract (2. Language): 
In this study, our objective is to develop a dsPIC based signal monitoring and processing system for analogue signals such as physiological originated signals (ECG, EMG, EEG, etc.). Microcontroller or microprocessor based monitoring systems can be much cheaper than PC based systems. However, the implementation of digital signal processing techniques using microcontroller is neither simple nor straight forward. The designed device consists of following hardware stages; a microcontroller adaptor board, dsPIC development board, (128×64) graphic LCD, and (4×4) keypad. Also, there are five different software modules which are ADC (Analog Digital Converter), FFT (Fast Fourier Transform), graphic LCD, keypad, and filter programs. The proposed device takes analogue signals via an ADC module and processes them with dsPIC by using keypad commands and then allows to plot at graphic LCD.
