A battery is a device that converts stored
chemical energy into electrical energy.
DC, AC & RMS
The three main components in a battery are the
anode, cathode, and electrolyte.
Direct Current (DC):
Current travels in only one direction in a

Active Filters and ECG Project Design
So far we have looked at passive filters. Passive filters do
not require any energy to operate beyond that supplied by
the signal source. Passive filters typically contain only
resistors, capacitors, and induct
