GENERAL DESCRIPTION The AD is an integrated signal conditioning block for electrocardiogram (ECG) and other biopotential measurement ://   In only 15 years, the power of personal computers has increased by a factor of nearly one-thousand.

By all accounts, it will increase by another factor of one-thousand in the next 15 years. This tremendous power has changed the way science and engineering is done, and there is no better example of this than Digital Signal ~o/MMS/materials/ W power at the coil, which resulted in an average flip angle of for the birdcage coil.

With dw ov ¼ 1 ms corresponding to the acquisition bandwidth of 1 MHz, two- j four-fold radial oversampling was performed. By starting data acquisition only 1 ms after the RF pulse, the total dead time D amounted to 5 ms ¼ j dw.

The output of this amplifier is sent to the respective band-pass filter, and such output is also used by the DSC as a reference to generate the adequate PWM feedback signal.

Filtering   A simple data acquisition system is composed of a multiplexed input stage, followed by an instrumentation amplifier that feeds one accurate and relatively expensive ADC. This arrangement saves the cost of multiple ADCs. Data Acquisition Block Diagram Fundamental Signal Conditioning Figure Rsource Ron A + – MUX R C Fig.

Usually the ECG signal acquisition hardware can remove the power line interference. However the baseline wandering and other wideband noises are not easy to be suppressed by hardware equipments.

Instead, the software scheme is more powerful and feasible for offline ECG signal X. Mo, N. Wary, and A. Chan Carusone, “High-Performance CMOS Clock Distribution,” in Phase-Locked Frequency Generation and Clocking: Architectures and circuits for modern wireless and wireline systems, Editor W.
