It depends on whether the capacitor is series or shunt. If series, capacitors block low frequencies. If shunt, capacitors block high frequencies.

If capacitors block the ac signals then why they are used in dc circuits?
Capacitors don't 'block' a.c. signals; they block d.c. signals. But there are lots of different reasons for using capacitors apart from their ability to block d.c. signals.

How are capacitors used in speaker applications?
Capacitors are used to limit the frequencies sent to speaker units in multiple speaker applications. As the frequency increases, so does the effective resistance of the capaitor. (known as reactance) For instance, tweeters only work efficiently with high frequencies. Applying low frequencies to these devices is inefficient and could cause harm to the unit. Putting a capaitor in line with it will only allow high frequencies through. Using a combination of capacitors and coils, in parrallel to form filters, can make only desired frequencies pass to the correct driver unit. Each speaker can then work most effeciently with the desired frequency. This is a fine art, to make sure that the sound is pure and not coloured or distorted and has to also match the cabinet in which the drivers are mounted.
Why coupling capacitor block DC in amplifier?
capacitors at input block dc and allows ac only. so absolute none of the dc enters the circuit. They are called decoupling capacitors or blocking caps. -DANNY S

What is LNB dish satellite?
Low Noise Block-down converter (so called because it converts a whole band or "block" of frequencies to a lower band). Thanks.
How many blank lines should appear between the date and the inside address in a business letter written in full block format?
In a full block format business later there should be four blank lines between the date and the inside address. Between your letterhead and the date should be two blank lines.
