Question

State the statement true or false: “BLPF has sharp discontinuity and ILPF doesn’t, and so ILPF establishes a clear cutoff b/w passed and filtered frequencies”.

(a) True

(b) False

I have been asked this question by my college professor while I was bunking the class.

I'd like to ask this question from Smoothing Frequency-Domain Filters topic in portion Intensity Transformations and Spatial Filtering of Digital Image Processing

Answer 1

Right answer is (b) False

For explanation I would say: ILPF has sharp discontinuity and BLPF doesn’t, so BLPF establishes a clear cutoff b/w passed and filtered frequencies.
