If the notch filter is the only crossover part on the driver, a series will have to do otherwise (for a parallel to work) you'd need to add a series resistor to take the energy within the filter band. All this is very generalised.

WebThe bandpass and notch (or band-stop) filters are designed to pass or block a specified range of frequencies. As a review, the primary frequencies are identified on the frequency response curves in Figure 1.As you can see, each of these filters has two cutoff frequencies, designated f C1 and f C2.The difference between the cutoff frequencies is … WebJan 8, 2024 · Basically the filter is a PLL that reacts with exponential decay to changes in the complex amplitude of the 50Hz component in its input, with a time constant that gets larger with the filter's selectivity. The signal passes without relevant delay; the delay only concerns how fast changes in the 50Hz component get tracked (and thus compensated).
WebApr 15, 2013 · The parallel notch filter that I used had the effect of raising the impedance peak about 8 ohms, but it sure did flatten out the FR curve quite nicely. Now if I move those same values of LCR to a series notch in parallel with the driver (B), I don't get the same results at all, and the simm'd FR is elevated considerably at 1.8kHz. WebNotch Filters are designed to reject narrow bandwidths while passing all others. Shop now with Edmund Optics! How may I help you? Engineers are available to assist.
