What is the impulse response of ideal low-pass filter?
Thus, the impulse response of an ideal lowpass filter is a sinc function.
How do you find the impulse response of a filter?
First, remember that the impulse response is literally "the response of a system to an impulse." If the input is an impulse (x[n]=δ[n]), then the output is the impulse response (y[n]=h[n]). which is sometimes written as a vector, like h[n]=[1,2] for n=0,1. so that the impulse response is defined in a recursive way.
What is impulse response in filters?
The impulse response (that is, the output in response to a Kronecker delta input) of an Nth-order discrete-time FIR filter lasts exactly. samples (from first nonzero element through last nonzero element) before it then settles to zero. FIR filters can be discrete-time or continuous-time, and digital or analog.
Is the ideal band pass filter causal?
the filter is not causal, i.e. the impulse response h(n) is non zero for n<0; the impulse response has infinite duration.
