they are used in industries so to able you to work on particular frequency and cut the other for e.g if you are working for high frequency then low frequency will be cut and vise versa
Earth is low pass filter, because it tends to absorbe the amblitude of the high frequency waves.
low pass or high pass
by combining a low-pass filter with a high-pass filter.[1]
A: i am afraid that will take total redesign.
Capacitor has many applications in electronics circuits, one of its application is in FILTERS. Mainly two types of Filters are formed with the help of capacitor namely, i)Low Pass Filter(LPF) ii)High Pass Filter(HPF) Impedance of capacitor is inversely propotional to the frequency, therefore a capacitor in series with resistor will act as Low Pass Filter. since all the high frequency are passed to ground.
Does not allow high frequencies to pass through the circuit.
low pass or high pass
A low pass removes frequencies ABOVE a set level. A high pass removes frequencies BELOW a set level. A separate high pass filter can be used to route only frequencies over, say, 80 Hz to your main speakers (if your receiver/processor did not have this function). Then you would set the low pass filter on the subwoofer to 80 Hz to reject signal above that level.
If the requirement is to pass low frequencies and block higher ones, it has every advantage and no disadvantages. For any other application it is useless.
low pass is for subs only it tells the amp to play low frequency only dont run subs on high pass or off
A low pass filter allows "low" frequencies to pass through a circuit and blocks higher frequencies.
To begin with there is a source of sound which is an oscillator which can have many different wave forms which include saw, square, triangle and sine. Then there is the filter section, there are 3 different types of filter which are high pass, low pass and band pass, the most common of which is the low pass. Which according to the amount will filter out the low parts of the frequency. Band and high pass do the same except they filter out the high and a specified band. Low frequency oscillators have the ability to modulate pitch, filter frequency and others. You than press a key and according to the setting explained above a certain noise comes out.
