LC filter

Introduction:
In electronics and communication field many type of filter is used .Like RC(register capacitor)filter ,RL(register inductor ) filter,LC(inductor capacitor )filter all of those are passive filter and active filter like Op-amps using filter etc.Most of this filter LC filter is widely used in radio broadcasting ,and any other communication field electronics equipments .It is very important section of equipment.It is used after power section mostly.It is used to pass the wanted signal and blocked the unwanted signal .It is also used to removed the ac(alternative current) ripple and only pass the DC(direct current) that means continuous wave.It is widely used to minimized the wave distortions.Now inductor or radio coil (choke) is easily find or made in home so LC filter is more popular in this field .They are followings type of LC filter :

  1. Low pass filter
  2. High Pass filter
  3. Band pass filter
  4. Band stop filter
  5. k-type constant filter

Note:This type is depends upon the location of inductor and capacitor i.e series or parallel to the input power and to those components.
