... a variety of circuits. These concepts permit you to create and understand a vast number of practical circuits using only two simple rules. The op-amps used in this experiment are fully compensated, i.e. the open-loop phase shift is less than 135o to reduce the danger of oscillation. However, for fut ...
Decibel notes
... One common use of dB’s in electronics is to compare different levels of power (Watts). For example the power output to power input ratio of an amplifier (Power Gain). The relationship between dB and Watts is: dB = 10 Log10 Watts. To determine the power ‘Gain’ of an amplifier, the ratio of power out ...
