Hey gd Question , but easy Pass band channel is the channel that passes all the frequencies in a region other than zero.The frequency band is divided into two main parts and the pass band channel will pass all frequencies above special limiting frequwncy.

What is Passband ripple?
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.
What is adjacent cell interference?
when imperfect receiver filter allow nearby frequencies to leak into the passband the interference produced is call adjacent channel interference Engr Aamir Naeem facebook id: Aamirnaeem77@gmail.com
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 near effect?
Adjacent channel interference nearby frequency leak into passband. The problem can be worse if an adjacent channel user is transmitting in very close range to a subscriber receiver. This problem is referred as near far affect. By Kazi Ashique Ahmed Rafi it usaully occurs in CDMA when users are transmitting unequal powers. by salman ahmed
What is near-far effect?

How do you convert the passband frequency into baseband frequency the range of 2Ghz passband?
Use the shifting property of the Fourier transform to shift the frequency response down to baseband. Multiply the time-domain signal by a complex exponential with the frequency of the amount you want to shift the frequency response.
What type of filter attenuates all frequencies above and below a specified passband?
Band-Pass filters

Advantages and disadvantages of butterworth filter?
Advantage is that it has the most flat passband meaning that it is very good at simulating the passband of an ideal filter. The disadvantage is that it has a horrible stopband because it gradually goes to zero so some parts of the stopband are still passed. However, for an nth-order Butterworth Filter, as n increases, the closer it is to an ideal filter. However, it is highly impractical to build a ridiculously high order Butterworth filter.
What has the author Harold Lee Broberg written?
Harold Lee Broberg has written: 'A three-pole analog cancellation filter with variable passband for use in range-gated radars'
