    This paper presents the development and construction of a multimodal biosignal instrument to monitor and analyse simultaneously for clinically relevant biosignals, obtained from both normal and pathological subjects. Biosignals were tapped from the appropriate locations of subjects’ bodies and buffered by operational amplifiers through disposable electrodes. This was directly followed by pre-processing the generated signals, feeding their outputs into an analogue to digital converter (ADC) input of 40PIC18F4450 self programmed microcontroller, and then fed into ADS1299 amplifier with supporting logics 74HC14 and HEF4050 respectively. The signals obtained were transmitted through 869.95 MHz frequency modulation transmitter with an improvised whip antenna, to stationary end consisting of FM receiver circuit connected to a 64 bit 4G RAM Computer, through a USB COM Port.
