Task 2 Design a 1st order low-pass filter with cutoff frequency 1kHz, 1) with roll-off and 2) without roll-off. For each filter, a) Provide the transfer function. b) Plot the step response of these filters. c) Plot the Bode frequency response of these filters. d) Compare the step and frequency responses of these two filters. e) Include the MATLAB code.

You can get complete answer in attached document.please have a look.

Explanation:

(2) Without rolloff, as given fc =1kHz Let us assume it is a first order RC filter ats transfer function is H(s)-RC RC withou

Then the transfer function becom

and step response is flat zero for without rolloff..

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
