High pass filter – It allows only higher frequencies, this done by allocating a cut off frequency which has a value of low frequency that can be allowed. In description it attenuates any low frequency.

Radio System Filters
A filter device is that used to allow or stop selected frequencies, or eliminate (filter out) any unwanted signals. In more technical, an RF filter is designed to allow attenuation or transmission of range of frequencies that would be applied. For an example, an RF filter helps to cut out RF interference (generally noise) that could occur if a hairdryer or lamp or else any noisy device is activated. RF filter used in different scenarios as per the requirement. Normally, there are basic four types of RF filters available in market.
