If maximum passband ripple is 0.1dB and signal-to-noise ratio is good, the ripple may not make a difference. But if zero passband ripple is required, then you need a Butterworth filter. daniel patrick sheerin obituary

Most power supplies are now switched mode designs. The filtering requirements for such power supplies are much easier to meet owing to the high frequency of the ripple waveform. The ripple frequency in switch-mode power supplies is not related to the line frequency, but is instead a multiple of the frequency of the chopper circuit, which is usually in the range of 50 kHz to 1 MHz.

Web3 de out. de 2024 · Ripple can be minimized by limiting charging current to the MOSFET. 3. Feedthrough Capacitors. It may occur to you that using a capacitor to smoothen the ripple is a good idea. But typical capacitors only help in filtering out low-frequency noise. To reduce high-frequency ripples, using a feedthrough capacitor is a better option. Weboutput. The noise typically shows up as high frequency spikes or ringing at the transition points on the ripple waveform. Thus, if a peak to peak measurement is made of the ripple and noise, the amplitude of the noise will generally be additive to the ripple voltage as shown in Figure 1. Figure 1.
