The 3-bit flash A/D converter in Figure has a reference voltage of VREF = 3.3 V. The 3-bit output is 101. What is the range of vA that produces this output?
An amplifier is to have an input of 100watts. Its effeciency is 75%, what is the maximum ambient temperature wherein this amplifier may be placed with a maximum junction temperature of 200degC and a junction to case thermal resistance.
An LTI system's impulse response is described by the differential equation, dh(t)/dt + 3h(t) = impulse function. Find the characteristic roots for the system, the initial condition, and the h(t) for t > 0.
It is desired to run the motor in the previous problem with a power factor of unity. To achieve this, a capacitor C is connected in parallel across the motor, which results in a circuit like that shown in Fig. 2.13. Calculate the value of C to ach..
