Web5 de out. de 2014 · Passband ripple does indicate that there will be some level of distortion in the signal -- the question is whether the level of distortion is acceptable. 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. 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.
