Study Notes
Filter Types and Characteristics
- Low-pass filters allow low frequencies to pass and attenuate high frequencies.
Low-Pass Filter Characteristics
- The amplitude-frequency characteristic is flat from 0 to fC (corner frequency).
- Frequency components above fC are greatly attenuated.
High-Pass Filter Characteristics
- The amplitude-frequency characteristic is flat from a certain frequency ~ ∞.
- The primary function of a high-pass filter is to allow frequency components above the corner frequency to pass through without attenuation.
Band-Pass Filter Characteristics
- The defining characteristic of a band-pass filter is that it allows frequency components within a specific frequency range to pass through.
- The amplitude-frequency characteristic becomes flat within a specific frequency range.
Band Stop Filter Characteristics
- The primary function of a band stop filter is to attenuate frequency components within a specific frequency range.
- The amplitude-frequency characteristic is flat outside of the specific frequency range.
Filter Functions
- The primary function of a low-pass filter is to allow low-frequency components to pass through and attenuate high-frequency components.
- The function of a band stop filter is to attenuate frequency components within a specific frequency range.
- There is no filter type that allows all frequencies to pass through without attenuation.
