A person applies a sine wave and square wave to an AND gate as shown in the figure (i) and (ii). Assuming that both the voltages are applied in phase, the person observes the output at E and F on (i) and (ii), respectively. [Assume minimun voltage of 5 V is equivalent to logic (i)] |

Answer» Square wave at 50 Hz and square wave at 100 Hz. (i) Sine weve , 50 Hz , 2 V ` (##ARH_5Y_SP_06_05_19_01_E02_038_S01.png" width="80%"> (ii) sine wave , 100 Hz , 8V  In figure (i) , sine wave and square wave both have different frequency , respectively , 50 Hz and 107 Hz. Hence, these voltages are not processed by AND gate, THEREFORE no output is obtined from gate (i) In figure (ii), sicnce wave and squarewave VOLTAGE are processed by AND gate . Since , logic gate (AND gate) gives output in two level (0 and 1) only at same frequency of input . Therefore , the output of gate (ii) will ve pulsed wave of 100 Hz. |
