Question

The maximum permissible duration between two samples of 5 kHz signal to ensure perfect reconstruction of the signal is

• A. $125\mu s$
• B. $45\mu s$
• C. $100\mu s$
• D. $90\mu s$

Answer 1

The correct option is C $100\mu s$

$T_s\le \frac{1}{2f_m}=\frac{1}{2\times 5\times {10}^3}{T}_{smax}=100\mu s$
