In differential amplifier the input are given as V1=30sin (50t)+10sin (25t) , V2=30sin (50t)-10 sin (25t), 0 =200,RE =1k and RC = 15k . Find the output voltages V01, V02 & gm=4M -1 |
| A. | V<sub>01</sub>=-60[10 sin u2061 (25t) ]-6.637[30sin u2061 (50t) ], V<sub>02</sub>=60[10 sin u2061 (25t) ]-6.637[30sin u2061 (50t) ]. |
| B. | V<sub>01</sub>=-6.637[10 sin u2061 (25t) ]-60[30sin u2061 (50t) ], V<sub>02</sub>=6.637[10 sin u2061 (25t) ]-60[30sin u2061 (50t) ]. |
| C. | V<sub>01</sub>=-60[30 sin u2061 (50t) ]-6.637[10sin u2061 (25t) ], V<sub>02</sub>=60[30 sin u2061 (50t) ]-6.637[10sin u2061 (25t) ]. |
| D. | V<sub>01</sub>=-6.637[30 sin u2061 (50t) ]-60[10sin u2061 (25t) ], V<sub>02</sub>=6.637[30 sin u2061 (50t) ]-60[10sin u2061 (25t) ]. |
| Answer» B. V<sub>01</sub>=-6.637[10 sin u2061 (25t) ]-60[30sin u2061 (50t) ], V<sub>02</sub>=6.637[10 sin u2061 (25t) ]-60[30sin u2061 (50t) ]. | |
