Question

@Ravikumar123 please don't answer this question please. I want someone else answer this.

--------------------------------------------------------------

Digital Signal Processing, please explain step by step how these two examples is solved about decimation and interploation in signal processing. Don't answer if you cant provide explaniation. Provide written English explanation, don't just solve it. And please also answer my main questions below images

1 . In Example 1 :

How did he found : y[n] = {4,3,7,3,4} please provide clear explaniation how did he calcualted it, and what is M=2 , how did he excluded terms from p[n] and found y[n] , i just wanted to know how did he found y[n] from p[n] when M=2

2. In Example 2:

How did he found : y[n]

Example: Decimation of x/n]-2, 6, 4, 2, 6, 8, 4, 2, 4, 4) fn] x[n] plnJ gain e-/2 hIn]- 1/2, 1/2) h[0]-1/2, h[1]-1/2 pln] = 'x[n] * h[n]{4,5,3,4,7,6,3,3,4,2} 2 y[n] = {4,3,7,3,4}

Explanation / Answer

Its simple

for example 1 (decimation) undersand like that

y(n) = p(M*n) here M = 2

So y(n) = p(2n)

Now put n = 0

y(0) = p(0) = 4 (1 st element)

put n = 1

y(1) = p(2) = 3 (3rd element)

put n = 2

y(2) = p(4) = 7 (5th element)

Same as above y(3) = 3 & y(4) = 4

So y(n) = {4, 3, 7, 3, 4}

Now for example 2

Here interpolation L=2

p(n) = x(n/ L) = x(n/2)

Now put n = 0

p(0) = x(0) = 1

put n = 1

p(1) = x(1/2) there is no element for this number so we assume 0

So p(1) = 0

put n = 2

p(2) = x(1) = 3

p(3) = again 3/2 not possible so = 0

same as above

p(n) = {1, 0, 3, 0, 5, 0, 3, 0, 7, 0}

now just linear convolution of p(n) & h(n) gives y(n)

Now I hope u will understand. Comment if u have other query

pls rate thumbs up. pls...
