Linear Regulator Fundamentals
Linear Regulator Fundamentals

... • A linear regulator operates by using a voltage-controlled current source to force a fixed voltage to appear at the regulator output terminal. The control circuitry continuously monitors (senses) the output voltage, and adjusts the current source (as required by the load) to hold the output voltage ...

... VA*cos(phase) is common, as is PF = 1/sqrt(1+THD2). Aren’t these the same? Not in the real world! The cos(phase) equation only yields the “correct” result when no distortion or other frequencies are present. The THD related equation only yields the “correct” result when there is no phase shift prese ...

... When λ=1.5, the delay is 1.5Ts and frd is fs/ 6. Fig. 5 shows the Bode plots of the open-loop gain T. The system is stable at the PCC point because the phase crosses -180º before fr due to the delay effect. Ref. [7] shows that if the resonance frequency is higher than fs/6, the resonance peak is not ...

Chirp spectrum



The spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar time-domain waveform, and the two versions are mathematically related by the Fourier transform. The spectrum is of particular interest when pulses are subject to signal processing. For example, when a chirp pulse is compressed by its matched filter, the resulting waveform contains not only a main narrow pulse but, also, a variety of unwanted artifacts many of which are directly attributable to features in the chirp's spectral characteristics. The simplest way to derive the spectrum of a chirp, now computers are widely available, is to sample the time-domain waveform at a frequency well above the Nyquist limit and call up an FFT algorithm to obtain the desired result. As this approach was not an option for the early designers, they resorted to analytic analysis, where possible, or to graphical or approximation methods, otherwise. These early methods still remain helpful, however, as they give additional insight into the behavior and properties of chirps.
