Abstract: This paper presents system design aiming to provide LOW COST solutions to the problems encountered in acquiring Electrocardiograph(ECG) signals in monitoring mode (ECG bandwidth--0.5-35Hz) from the body, as well as providing remote transmission of ECG data through Telemetry. Two separate devices have been constructed to achieve the overall goal. Overall hardware design includes three parts namely front end analog section (acquisition), processing section, and transmission section (telemetry). The software part is implemented using visual basic to get real time data display which is required for continuous monitoring of the patient. This paper aims on achieving minimum possible cost for acquiring ECG signal. The system implemented also allows advance warning operations of heart abnormalities.

Abstract: This paper presents the tunable technique of the analog filter at high frequency fp = 1 MHz by used the Fractional-order (n+α) step, where n is an original of integer-order on circuit and a is an approximation order step 0 < α < 1 , An approximation order is designed from the Fractance circuits, and also presents the approximation function of the Fractional-order Laplacian Sα design on the OTA low-pass filter circuit. This circuit used single active component. OTA and CFA components are in monolithic chip (IC LT1228).The CFA design with the Fractional-order elements to feedback control the OTA for relative stabilty gain of amplifier. The results shown that tunable filter by Fractional-order step technique provides the flat passband and reduced the peaking problem and improved slope of magnitude response of filter and result comparable with high-order filters
