electronic filter
electronic circuit that removes unwanted components from the signal, or enhances wanted ones, or both
capacitor-input filter
type of filter
notch filter
band-stop filter with very narrow stopband
band-stop filter
filter that passes signals outside a certain frequency range, and attenuates signals within that range
active filter
a type of analog circuit implementing an electronic filter using active components, typically an amplifier
Comb filter
signal processing filter
infinite impulse response filter
property of many linear time-invariant (LTI) systems
low-pass filter
filter that passes signals with a frequency lower than a certain cutoff frequency, and attenuates signals with higher frequencies
elliptic filter
signal processing filter
voltage-controlled filter
type of electronic filter circuit controlled with voltage
band-pass filter
filter that passes signals within a certain frequency range, and attenuates signals outside that range
electronic filter topology
electronic filter circuits without taking note of the values of the components used but only the manner in which those components are connected
Finite Impulse Response filter
type of filter in signal processing
Gaussian filter
filter in electronics and signal processing
digital filter
mechanism to reduce or enhance aspects of a sampled, discrete-time signal
audio crossover
type of electronic filter circuitry for audio applications, especially for loudspeaker boxes; thereby mostly analog, very seldom digital
distributed element filter
type of electronic filter circuit
waveguide filter
electronic filter that is constructed with waveguide technology
high-pass filter
filter that passes signals with a frequency higher than a certain cutoff frequency, and attenuates signals with lower frequencies
Line filter
type of electronic filter
Bessel filter
type of analog linear filter in electronics
all-pass filter
filter that passes signals of all frequencies with same gain, but changes the phase relationship among various frequencies
Adaptive filter
system with self-optimizing transfer function
Butterworth filter
type of signal processing filter designed to have a frequency response as flat as possible in the passband
Crystal filter
electronic filter
