It is desired to build a sampling system which takes a recorded orchestral music signal s(t) and converts it to a discretely-sampled form. In order to experimentally determine the bandwidth (in frequency) of this signal the best transform would be (circle the correct answer or answers and then justify your answer(s), for all choices you circled): i) The Fourier transform of a continuous function or a discrete sequence ii) The z-transform iii) The Fourier series iv) The discrete Fourier transform

its c or d   take a lucky guess my dude

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
