Electronics and Communication Control Systems Difficulty: Medium

The steady-state response of a network to the excitation Vcos(ωt + φ) may be found in three steps. The first two steps are as follows: 1. Determining the response of the network to the excitation e jωt . 2. Multiplying the above response by $$\overline {\text{V}} $$ = Ve jφ . The third step is When a current carrying conductor is brought into magnetic field, the force that moves the conductor depends upon If the electric field established by three point charges Q, 2Q and 3Q exert a force 3F on 3Q and 2F on 2Q, then what is the force exerted on the point charge Q? A digital displacement indicator based on a linear voltage differential transformer (LVDT) transducer and A/D conversion used a LVDT with a sensitivity of 1 mV/mm. If the smallest displacement to be measured is 0.1 mm and the maximum displacement of the LVDT core is 10 cm, then the digital display required for the instrument has to be Raman and Brillouin scattering are usually observed at . . . . . . . .
