An input of Vsinωt is applied to an ideal frequency doubler. Compute its output voltage?$ |
| A. | V<sub>o</sub> = [(V<sub>x</sub>×V<sub>y</sub>) /V<sub>ref</sub><sup>2</sup>] × [1-cos2ωt/2]. |
| B. | V<sub>o</sub> = [(V<sub>x</sub><sup>2</sup>×V<sub>y</sub><sup>2</sup>) /V<sub>ref</sub>] × [1-cos2ωt/2]. |
| C. | V<sub>o</sub> = [(V<sub>x</sub>×V<sub>y</sub>)<sup>2</sup> /V<sub>ref</sub>] × [1-cos2ωt/2]. |
| D. | V<sub>o</sub> = [(V<sub>x</sub>×V<sub>y</sub>) /( V<sub>ref</sub>] × [1-cos2ωt/2]. |
| Answer» D. V<sub>o</sub> = [(V<sub>x</sub>‚Äö√†√∂‚àö‚â•V<sub>y</sub>) /( V<sub>ref</sub>] ‚Äö√†√∂‚àö‚â• [1-cos2‚âà√¨‚àö¬¢t/2]. | |
