General Characteristics
   Filter Class       
   Your choices are...         
   Continuous       A continuous filter has a continuous time operation. 
   Switched Capacitor       Switched capacitor filters are clocked devices. The input signal is sampled at a high rate and processed discretely instead of on a continuous-time basis. 
   Other       Other unlisted filter classes. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Filter Type       
   Your choices are...         
   All Pass       All pass filters (phase shift filters) do not affect the amplitude of the signal. Instead, they change the phase of the signal without changing its amplitude. 
   Band Pass       Bandpass filters are used to attenuate frequencies above and below a range of frequencies called the bandwidth or passband of the filter. Any signal with a frequency within the bandpass range passes through the filter. Any signal with a frequency outside the bandpass is reduced. 
   Band Reject       Band reject filters (band stop filters, notch filters) are used to attenuate a range of frequencies and allow all other frequencies to pass. 
   High Pass       High pass filters attenuate frequencies above a particular frequency called the cut-off frequency. Frequencies higher than the cut-off frequency pass easily through the filter. 
   Low Pass       Low pass filters attenuate frequencies below a particular frequency called the cut-off frequency. Frequencies below the cut-off frequency pass easily through the filter 
   Universal / Programmable       Universal filters can be configured by the user to function as a low pass, high pass, band pass, or band stop filter. 
   FIR       Finite impulse response (FIR) filters are digital filters whose response to a unit step function eventually results in a zero output. 
   IIR       Infinite impulse response (IIR) filters are digital filters whose response to a unit step function is not zero over an infinite time interval. 
   Biquad       Biquad filters are special digital filters with two poles and two zeroes. 
   Other       Other unlisted filter types.

   Filter Characteristic       
   Your choices are...         
   Bessel       Bessel filters are active filters with a passband that maximizes the group delay at zero frequency, thus showing a constant group delay in the passband. Group delay is a measurement of the time it takes for a signal to move between two points in a network. A constant group delay in the passband of filters implies that for all signals with frequencies in the passband, the time delay will be the same. This fact is important in many applications, especially audio, video and radar applications. 
   Butterworth       Butterworth filters are designed so that the frequency response is flat in the passband. 
   Chebyshev       Chebyshev filters feature a very steep roll-off, but have ripples in the passband. 
   Elliptic       Elliptic filters (Cauer filters) exhibit equalized ripple in both the passband and the stopband. 
   Gaussian       Gaussian filters produce no overshoot in response to an input step. They optimize the rise and fall times. 
   Legendre       Legendre filters are designed to produce the maximum roll-off rate for a given order and a flat frequency response in the passband. 
   Other       Other unlisted filter characteristics.
