How do I know my bandpass filter?
The centre frequency of the band pass filter which is also termed as 'resonant peak' can be formulated by using the below equation: fc = 1/2π√(LC) Where L = inductance of an inductor whose units are in Henry (H). C = capacitance of a capacitor whose units are in Farad (F).
How do you identify a filter from pole-zero plot?
Well if the pole is more closer to the origin, i.e, if it's pole dominant then the system is LPF. Similarly, if it's zero dominant it's a HPF. low pass filters will be pole dominant whereas HPFs will be zero dominant and all pass filters will have a symmetrical arrangement of poles and zeroes!
How do you read a pole-zero plot?
By convention, the poles of the system are indicated in the plot by an X while the zeros are indicated by a circle or O. A pole-zero plot can represent either a continuous-time (CT) or a discrete-time (DT) system. For a CT system, the plane in which the poles and zeros appear is the s plane of the Laplace transform.
What does it mean if a pole is zero?
Poles and Zeros of a transfer function are the frequencies for which the value of the denominator and numerator of transfer function becomes zero respectively.
