TO SOLVE Exercise 27.4 (truncation) For fC(R), show that there exists φ E (R) that agrees with f on [-1, 1]. FOR REFERENCE, DO NOT SOLVE The basic idea for generalizing the notion of function in the context of distributions is to regard a function as an operator Ty (called a functional) acting by integration on functions themselves: and integration by parts shows that Ty(y) - 15.1.7 Definition (R) (or (I) will denote the...
Exercise 27.1 Are the following functionals distributions? (a) T(p) Ip(0) (b) T(p)= а, а ЕС. Σ φ(n) (0). (c) T(p) n=0 27.2 The space (IR) of test funct i. One is led naturally to require that test functions he and have bounded support. The space of nitely 9 (R) or simply 9 (recall Definition 15.1.7), est functions y differentiable is denoted by of these functions vanishes outside a bounded interval (which depends on e). (İİ) ф is infinitely differentiable in...

Exercise 21.1 Assume that f is in Li (R) and g(z) = e2i". Compute f*g. 20.1.1 Definition The convolution of two functions f and g from R to C is the function f g, if it exists, defined by f * g(x) = | f(x-t)g(t) dt f(u)g(z-u) du. If no assumptions are made about f and g, the convolution is clearly not defined. Take, for example, f =...

Hello, I'm taking signal systems course. please solve this
question in matlab as soon as possbile please.
Question 1 a) Write a function that calculates the Continuous Time Fourier Transform of a periodic signal x() Syntax: [w, X] = CTFT(t, x) The outputs to the function are: w = the frequencies in rad/s, and X = the continuous Fourier transform of the signal The inputs to the function are: x-one period of the signal x(t), andt the time vector The...
please i need the question 15 for the detailed proof and
explaination ! thanks !

8. (a) If f(t) /2 show thattf. Use formulae from Question 4 to show thatpwF (the same equation in the transformed variables). It follows that F(w) - Ae-/2; evaluate the arbitrary constant A by putting w 0. Deduce that F(w) f(w) (i.e., this function is equal to its Fourier transform) (b)" Using Question 4(i), show that Fe-t2/202)-ơe_ơ2w2/2.
