Question

how can we find the impulse response of a moving average system in discrete time & how can we find the output of a given system if we know its input as impulse????

Answer 1

Translate the expression into a word phrase.

k + 12

A.
a number less than 12

B.
12 more than a number

C.
the product of a number and 12

D.
the quotient of a number and 12

Answer 2

Signals And Systems?? Convolution?

Answer 3

DSP not S&S but yup its related 2 convolution

Answer 4

excuse me ... help me.. m in great trouble...

Answer 5

\[y[n]=1/5 \sum_{4}^{0} x(n-k)\]

Answer 6

is the relationship b/w input & output n we have to find impulse response of MA system

Answer 7

MA??

Answer 8

moving average system

Answer 9

one million

Answer 10

??? means

Answer 11

MA = one million

Answer 12

\[x[n]=\cos(w0n)\]

Answer 13

didn't get ur rep... sumanta

Answer 14

\[y[n]=\frac{1}{5} \sum_{k=4}^{0} x(n-k)\]

Right??

Answer 15

how it can be 4 to 0??

-4 to 0??

Answer 16

Write your question properly.. :)

Answer 17

sorry its 0 to -4

Answer 18

:S

Answer 19

answer plz...

Answer 20

\[y[n]=\frac{1}{5} \sum_{k=-4}^{0} x(n-k)\]

Answer 21

For Impulse Response:

Replace input \(x[n]\) by \(\delta[n]\), and \(y[n]\) by \(h[n]\)..

Answer 22

\[h[n]=\frac{1}{5} \sum_{k=-4}^{0} \delta(n-k)\]

Answer 23

just this is the answer
???

Answer 24

NO..

Answer 25

Evaluate this.. :P And I don't know how to do that..

Answer 26

n again sorry.. m in great stress.. limits are 0 to +4...

Answer 27

u dnt know??

Answer 28

\[h[n]=\frac{1}{5} \sum_{k=0}^{4} \delta(n-k)\]

Answer 29

Here, I know one formula, but I don't know to apply that:

\[\sum_{k=0}^{\infty} \delta(n-k) = u[n]\]

Answer 30

Moreover, it can be:

\[h[n] = \frac{1}{5}(\delta(n) + \delta(n-1) + \delta(n-2) + \delta(n-3) + \delta(n-4))\]

Answer 31

\[h[n] = \{\underline{\frac{1}{5}}, \frac{1}{5}, \frac{1}{5}, \frac{1}{5}, \frac{1}{5}\}\]

Answer 32

\(n=0\) at first \(\frac{1}{5}\), then n = 1, 2,3, 4..

Answer 33

I am not sure, if I am true, just I have solved it as my Heart guided me.. :P

Answer 34

i think ur brain guided u ri8.. ys its the correct ans.. i have cnfmed it ..

Answer 35

No, actually it was my Heart not brain, that's why I took a hell of time to solve it, if it would have been a brain, then it would have been done in a jiffy.. :P

Answer 36

Actually, Digital Signal Processing is a subject which bases itself upon Signals And Systems, so as I am doing Signals And Systems, so may be I can help you.. :)

But you have to give me time, I am no expert in it, I will take my time to tell you.. :) Because, I don't want to tell anyone here a wrong thing ever.. :)

Answer 37

I have posted this post's link on the post where you asked about Time Period of Discrete time, so please delete that, I can't do that because my net is taking revenge from me.. :) It is going slow like a turtle.. :)
