The minimum step size required for a Delta modulator operating at 36 samples/sec to track the signal (here u(t) is the unit step function) x(t) = 125t (u(t) - u(t - 1)) + (250 - 125t) (u(t - 1) - u(t - 2)) So that slope overload is avoided, would be
Answer : Option B
Explanation :
To avoid slope overload
|m(t)| ≥ Δ . fs or |x(t)| ≥ Δ . fs
125 ≤ Δ . 25 . 210
27 ≤ Δ . 215 Δ ≥ 2-8.
