what is low pass filter and high pass filter?
what is the meaning of low pass filter and high pass filter? what are the components used to build it? And how does it work?
Low pass filter is a series of electronics used to forward the low frequency and discard or weaken the high frequency
while the high pass filter is a series of electronics used to forward high frequencies and discard or weaken low frequencies
A simple example of using low pass filters and high pass filters is on tone control and in loudspeaker crossover circuits
Read the crossover series
The main component for making low and high pass filters is very simple only requires capacitors and resistors otherwise it can also be added inductively to get better output results
working principle of low pass filter and high pass filter
As described above Components used to create low pass filters and high pass filters are capacitors and resistors
how does low and high pass filters works?
In order to more easily understand about the workings of low and high pass filter then you must first understand how the capacitor works
On the capacitor the smaller the capacity of the capacitor the lower the tone will be more difficult to pass through. For more articles about capacitors please read on what is capacitor and how does it work?
low pass filter RC
A simple low pass filter can be made using resistors and capacitors and therefore this circuit is often referred to as a low pass RC filter
to more easily understand how the low pass filter work please look at the following picture
In the above circuit if the capacitor capacity size is enlarged then the higher frequency will be more difficult to enter because will be discharged by the capacitor
The above circuit will pass or pass only low frequency

high pass filter RC
To understand about how the high pass filter works notice the picture below
different from the low pass filter on the high pass filter capacitor arranged in series so if the capacitor value is reduced the low frequency will be difficult to enter while for high frequency will be passed
Use a low pass filter can also meet on the tone control circuit
