Given a sequence x[n], to generate the sequence y[n] =x[3 – 4n], which one of the following procedures would be correct?
  • a)
    First delay x(n) by 3 samples to generate z1[n]then pick every 4th sample of z1[n] to generate z2[n], and than finally time reverse z2[n] to obtain y[n].
  • b)
    First advance x[n] by 3 samples to generate z1[n], then pick every 4th sample of z1[n] to generate z2[n], and then finally time reverse z2[n] to obtain y[n]
  • c)
    First pick every fourth sample of x[n] to generate v1[n], time-reverse v1[n] to obtain v2[n], and then finally advance v2[n] by 3 samples to obtain y[n]
  • d)
    First pick every fourth sample of x[n] to generate v1[n], time-reverse v1[n] to obtain v2[n], and finally delay v2[n] by 3 samples to obtain y[n]
Correct answer is option 'B'. Can you explain this answer?

Given a sequence x[n], to generate the sequence y[n] =x[3 – 4n],...
In option A,
z1[n] = x[n-3]
z2[n] = z1[4n] = x[4n-3]
y[n] = z2[-n] = x[-4n-3] ≠ x[3-4n]
In option B,
z1[n] = x[n+3]
z2[n] =z1[4n] = x[4n +3]
y[n] = z2[-n] = x[-4n+3]
In option C,
v1[n] = x[4n]
v2[n] = v1[-n] = x[-4n]
y[n] = v2[n+3] = x[-4(n+3)] ≠ x[3-4n]
In option D,
v1[n] = x[n]
x2[n] = v1[-n] = x[-4n]
y[n] = v2[n-3] = x[-4(n-3)] ≠ x[3-4n]

Given a sequence x[n], to generate the sequence y[n] =x[3 – 4n],...
To generate the sequence y[n] = x[3n], we need to sample the sequence x[n] every third sample.

The sequence y[n] can be expressed as y[n] = x[3n] for n = 0, 1, 2, ...

So, for each value of n, we need to find the corresponding sample in the sequence x[n] and assign it to y[n].

For example, if x[n] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ...], then

y[0] = x[3*0] = x[0] = 1
y[1] = x[3*1] = x[3] = 4
y[2] = x[3*2] = x[6] = 7
y[3] = x[3*3] = x[9] = 10
...

So, the sequence y[n] would be [1, 4, 7, 10, ...]
