Abstract
Portable multi channel system is described for the recording of biomedical signals wirelessly. Instead of using the conversional time-division analog-modulation method, the technique of digital multiplexing is applied to increase the number of signal channels to four. Detailed design considerations and functional allocation of the system is discussed. The front-end unit is early designed to condition the input signal in an optimal manner. Then, the micro controller handled the tasks of data conversion, wireless transmission, as well as providing the ability of simple preprocessing such as waveform averaging or rectification. The low-power nature of this micro controller affords the benefit of battery operation and hence, patient isolation of the measurement system.
