Our ECG amplifier/filter board schematics is derived from an Analog Devices
application handbook. We adapted and complemented it to suit our needs and we used PCB123 Schematic
to draw the circuit schematics. Then, we used PCB123 Layout
to draw the actual board. PCB123 is a great program and it's entirely free, so you can get it here
The microprocessor unit was made by a member of our team some years ago and at its core lies a PIC microcontroller.
To plot data on a laptop screen, we needed software that could simulate an oscilloscope. For that we used the excellent (and free) Oscilloscope.dll
, written by Michael Bernstein. We thank him for his kind support.
Furthermore, we also prepared a list of components that is just too big to show up here. From our website, you can download this list, every schematic and layout we've made.
