# Long description

This figure is a block diagram showing how signals from the heart can be detected, processed and displayed. A set of signals from the heart are picked up by an electrode sensor within the wearable ECG device. Still within the device, these signals are sent through an analogue interface with signal conditioning, then an analogue-to-digital converter, then a high-pass filter, and finally a notch filter. The signal then leaves the wearable ECG device and enters a wireless transmitter, from which it is sent to a wireless receiver attached to a computer. The computer carries out signal processing, after which the processed signal may be displayed or stored.
