The bandwidth, , or f1 to f2, of a damped oscillator is shown on a graph of energy versus frequency. The Q factor of the damped oscillator, or filter, is . The higher the Q, the narrower and ‘sharper’ the peak is.  Higher Q indicates a lower rate of energy loss relative to the stored [Continue]

Gain is a measure of the ability of a two port circuit to increase the power or amplitude of a signal from the input to the output port. It is often expressed using the logarithmic decibel (dB) units A gain greater than one (zero dB), that is amplification, is the defining property of an active [Continue]
