According to the sampling theorem for low pass signals with T1=1/B, then what is the expression for us(t) = ? |
| A. | ( sum_{m=- }^ u_c (mT_1) frac{sin u2061( frac{ }{T_1}) (t-mT_1)}{( frac{ }{T_1})(t-mT_1)} ) |
| B. | ( sum_{m=- }^ u_s (mT_1- frac{T_1}{2}) frac{sin u2061( frac{ }{T_1}) (t-mT_1+ frac{T_1}{2})}{( /T_1)(t-mT_1+ frac{T_1}{2})} ) |
| C. | ( sum_{m=- }^ u_s (mT_1- frac{T_1}{2}) frac{sin u2061( frac{ }{T_1}) (t-mT_1- frac{T_1}{2})}{( frac{ }{T_1})(t-mT_1- frac{T_1}{2})} ) |
| D. | ( sum_{m=- }^ u_c (mT_1) frac{sin u2061( frac{ }{T_1}) (t+mT_1)}{( frac{ }{T_1})(t+mT_1)} ) |
| Answer» C. ( sum_{m=- }^ u_s (mT_1- frac{T_1}{2}) frac{sin u2061( frac{ }{T_1}) (t-mT_1- frac{T_1}{2})}{( frac{ }{T_1})(t-mT_1- frac{T_1}{2})} ) | |
