For the signal x(t) shown below, find X(w) using differentiation property. x(t) 1 -2 -1 1

Find the transforms of the following waveforms a) f(t) = [2+2sin2t – 2cos2t] u(t) b) f(t) = 3[1- e 10] u(t) c) f(t) = -58(t) + 50u(t)

Consider the function given below. Determine whether the given function is causal and BIBO-stable. x(t) = 4 rect (t/2)   Please show work

Can anyone help me with This circuits question. Please don’t use Laplace transform 

Waveform synthesis Below, use the symbol r(t) for the ramp function and u(t) for the step function. Write the expression of æ1 (t) below in terms of ramp and step functions:|| x1 (t) 2 -3 -2 -1 0 1 2 3

3. A discrete time signal x(n) is shown in figure below x(n)t -2 -1 0 1 2 3 4 Sketch the signal x(n)u(2 – n) 1/2

/Sketch each of the following waveforms:- 1- i(t)= 2u (t-2)-(-2) +r(t-4) 2- v(t) = u(t-2) + u(t+2)

Can you solve this problem, using matlab? Thank you.
