The ideal passband of a receiver should have steep sides and a flat top. However many receivers use stacked filters to create the passband, and consequently the top of the passband sometimes has a ripple on it. This can cause distortion of the received signal.

What are the disadvantages of passive filters?

» There is no isolation b/w input and output. » These circuits can not provide any gain. » There is always someloss of signal, It can be in the passband. » Circuit becomes bulky if inductors are used. » There is no clear demarcation between Passband and stopband but actually it (Passband & Stopband) get mixed up. » In this frequency response is not sharp as no sudden change in the output when switching from passband to stopband. » Source loading can take place.


Will light pass through two successive colour filters?

Yes, if the passband of the first filter includes that of the second one, and the light contains wavelengths that fall within their common passband.

What is a ripple?

Ripple is the oscillations that can arise in a circuit when a signal changes suddenly. It stems (in analog circuits at least) from stray capacitances and inductances forming a resonator.Answer--Ripple can refer to: * Ripple (charitable organisation)* Ripple effect, the socio-educational phenomenon* Ripple (electrical), residual unwanted variations following ac to dc conversiono Frequency domain ripple, the ripple of a filter's insertion loss* Ripple (fluid dynamics) for capillary waves* Ripple, Kent, a village in Kent, England* Ripple, Worcestershire, a village in Worcestershire, England* Ripple marks, as identified in sediments and sedimentary rocks* Ripple monetary system* Ripple (wine)it is also a cheerleading move! it is when you take a step clap turn take a step yurn and you bend your knees do a high v put your arms together to the side bring it to you and swing your arm then jump *smile*


Are there any non-butterworth implementations of Linkwitz-Riley Crossover arrangement?

It depends on how you look at it; the Butterworth filter is probably the only filter with absolutely flat response in the passband, and the knees/slopes of the filters of the Butterworth filters add upp more or less perfectly at the crossover (for example in a loudspeaker filter). The Linkwitz-Riley is built up through putting two filters in cascade, and it has an absolutely flat passband. As soon as you find a filter that can be arranged in cascade and that has an absolutely flat passband; you're there! And when/if you're "there", you will probably come to the conclusion that the filter you found turned out to be a Butterworth... =/ Some might yell out: "what about ChebyshevII?" Well, that one does not have that smooth knee of the Butterworth, and it has the stopband ripple that has to be taken into account. Here's an idea: Throw together two Chebyshevs in cascade (series) and find a good motivation to why it's a good filter, and you can name it after yourself. Sick but true!

Unit of ripple factor?

Ripple, in DC power supplies, is technically unitless. Ripple voltage is specified in Volts/Volt, or a percentage. For example, a 12VDC power supply with 120mV (pk-pk) of ripple voltage is (0.12/12) = 1% ripple voltage.
