Document Summary

The common mode gain is a but when the inverting and non inverting amplifiers are joined at some node in theory, this is 0, causing a cmrr of 0. We want the signal to noise ratio to be high. Impedance is the ac analogue of dc resistance and is measured in ohms. Slightly more complicated because you have to consider the frequency of the current. Capacitors store electric charge in an electric field. Even when the capacitor is disconnected from a power source, it keeps its potential difference. They can block dc while allowing ac current to flow. They smooth the output of power supplies. They can be used to tune radios. When connected to positive and negative terminals, electrons are dragged away from one end of the capacitor and deposited in the other end. For there is an exactly equal and opposite amount of charge in either end of a capacitor.
