Web2.5 Normalised first-order low-pass filters. A graph of gain function against frequency is called a frequency response or a Bode plot. A normalised first-order low-pass frequency response (or Bode plot) is shown in Figure 9. … http://www.firstprogress.com/
WebThe order of the filter reflects the number of elements that delay your sampling by one - i.e. a first-order filter needs one sample to produce your desired output, a second-order filter needs two samples, etc. Here are some examples I'm pulling off google images: First order low-pass Butterworth filter: Second order low-pass Butterworth filter: There are many different types of filter circuits, with different responses to changing frequency. The frequency response of a filter is generally represented using a Bode plot, and the filter is characterized by its cutoff frequency and rate of frequency rolloff. In all cases, at the cutoff frequency, the filter attenuates the input power by half or 3 dB. So the order of the filter determines the amount of additional attenuation for frequencies higher than the cutoff frequency.

A first-order (single-pole) Active High Pass Filter as its name implies, attenuates low frequencies and passes high frequency signals. It consists simply of a passive filter section followed by a non-inverting operational amplifier. The frequency response of the circuit is the same as that of the passive filter, except ...
