Gain and bandwidth of frequency parameters

Measuring Signals Electronic circuits fall into two broad categories—those that process and transform signals and those that measure signals. Circuits that measure RF signal strength, whose fundamental metric is power, are generally called detectors, but only a thermopile bolometer measures this quantity directly. Integrated-circuit detectors invariably operate on a voltage sample of the signal to be measured. Circuits of this class are classified by the type of signal transformation they provide. Most often, these are bandpass filters partially characterized by a quality factor, Q, and a bandwidth, BW.

Gain BandWidth VS Unity Gain Bandwidth??

There exists enough books on active and passive filter design to fill a modest office library, however, there are certain aspects of the relationship between bandwidth as expressed in octaves versus Q that are poorly documented — if at all.

Definitions and Review A bandpass filter is characterized by three major parameters: Center frequency is the frequency at which the amplitude is maximum; gain is the maximum amplitude response occurring at the center frequency; and bandwidth or passband is the frequency range between the -3 dB points located on either side of the center frequency.

Bandwidth is expressed in several ways: Far and away, the most common audio usage is to express bandwidth in octaves.

A third situation arises where only Q is known and the BW in octaves is desired. This calculation is not obvious — nor easy. The next section presents the necessary closed solutions for each of these calculations. For reference purposes, Figure 1 shows a bandpass filter with its associated parameters labeled for clarity and is used for derivation purposes.

Let where y is any positive real number. Define N as the number of octaves of BW, i.Accurate Gain/Phase Measurement at Radio Frequencies up to GHz. by John Cowles and Barrie Gilbert Download PDF Introduction: Measuring Signals.
