This article continues from a previous one, “Bandwidth from Transfer Functions” to consider some aspects of frequency response above bandwidth. These include approximation of the unity-gain frequency ...

It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response—no good reference exists that defines this in simple terms. It seems ...

Dynamic signal analyzers (DSAs) have been a mainstay of test and measurement for almost 20 years. These versatile instruments, which analyze sub-100-kHz signals in both the time and frequency domain, ...
