The block diagram of a motor-control system with tachometer feedback is shown in Fig. 2P-46. Find lhe range of the tachometer constant K, so lhal the system is asymptotically stable.
Given the function F(a,b,c,d)=a'b+ad'+ab' a) Design a minimum two-level NOR-gate network to realize the above function. b) Design a minimum three-level NOR-gate network to realize the above function.
Suppose that we want to design an amplifier that can produce a 100-kHz sine-wave output having a peak amplitude of 5 V. What is the minimum slew-rate specification allowed for the op amp?

A 25-kVA load with power factor 0.80 lagging has a group of resistive heating units added at unity power factor. How many kW do these units take, if the new overall power factor is 0.85 lagging
Determine the panel orientation you would choose to obtain maximum energy: (a) Over the year (b) In the summer (c) In the winter Discuss your choice of slope angles if the location is at 75°N.
A system is called complex if a real-valued input can produce a complex-valued output. Suppose a linear, time-invariant complex system has an impulse response of h(t)= j[u(-t+2)-u(-t)]
In order to measure the heart rate of the patient, you acquire 8000 datapoints at the Nyquist sampling interval. What is the spectral resolution of the frequency spectrum resulting from these data?
An op-amp is connected in the noninverting amplifier configuration. A gain of 21 is achieved using resistors ofvalue 1Mohm and 50 kohms in the feedback circuit. The signal source is connected to the v+ terminal via a 100 ohm resistor.
If a computing system needs two 32Kbytes to store its program and 16Kbytes to store temporary data, will a 16-bit address bus sufficient
∂Δnp/∂t = DN∂2Δnp/∂x^2 -Δnp/τn + GL is known as the minority carrier diffusion equation for electrons. (a) Why is it called a diffusion equation (b) Why is it referred to as a minority carrier equation
