![]() The design relies on a recently introduced optimally-factored FIR filter method. This work presents a novel low-complexity noise suppression reconfigurable finite impulse response (FIR) filter structure for wearable ECG and heart monitoring devices. Limited device size, power consumption and cost are critical issues that need to be carefully considered when designing any portable health monitoring device, including a battery-powered ECG device. The ECG signal can be contaminated by various types of noise and artifacts (e.g., powerline interference, baseline wandering) that must be removed or suppressed for accurate ECG signal processing. Or macOS 10.14 & above.Wearable and implantable Electrocardiograph (ECG) devices are becoming prevailing tools for continuous real-time personal health monitoring. Moveable license: deactivate and reactivate on a new computer.Export averaged response in a variety of formats.Four averaging modes: Complex, Power (flat phase), Power (minimum phase) and Power (minimum phase + reference excess phase).Auto time alignment with manual adjustment.Load up to 200 measurements of any type.Rewindow longer FIR filters to the LAKE & Powersoft tap limits.
