Consider a permanent magnet dc motor with the following parameters; Ra = 0.35 ohms, La = 1.5 mH, Ke= 0.5(V/(rad/s)), Kt= 0.5 Nm/A and Jm = 0.02kgm^2. The rated torque of this motor is 4Nm. If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
Use a modulation index of 50 percent and a sampling rate of 160 kHz. In this project, develop a coherent demodulation for the modulated signal. Assume there is no channel error.
A serial transmission is set up for 8 bits with odd parity. The first two bytes of data are 01110111 with parity bit 1 and 01101010 with parity bit 0. From this we know that there are no errors in transmission.
Design the system which finds the most popular (one most often generated) symbol called winner in each block of 32 input symbols. The system reports the number of winners and their value. Use only 2 data inputs multiplexers and shift registers.
how does Intel's architecture differ from MiPS?
Design a datapath that consists of four four-bit, general-purpose registers and one four-bit processor status word (PSW) register. There are four status bits, carry, overflow, sign, and zero; these will be stored in the four bits of the PSW.
A 3-phase, 11 kV, round-rotor synchronous generator delivers power to an infinite bus whose line-to-line voltage is constant at 11 kV rms. The effective stator resistance and synchronous reactance per phase of the synchronous generator are respectiv..
an amplifier with a 1 MHz bandwidth and a 20 micro-V input signal. The input noise = 1 micro-V, output signal = 6.0 mV, and output noise = 1 mV. Find (a) SNR at the input Pin = Pn(in)= K(T)BW= 1.38*10-23(290)1MHz= 4*10-15W
To keep them running, some users created their own 25 Hz power in the plant using motor-generator sets. A motor-generator set consists of two machines connected on a common shaft, one acting as a motor and the other acting as a generator.
Control Systems- PID Controller, Which one of the following statements regarding the operation of a PID controller is definately false?
An engineer needs to detect a binary strings of any length or composition provided that each contains at least one substring of "1101". a) Draw the state diagram of this finite state machine.
A number stored in IEEE single precision floating point format has S=0, E=0111 1101, and F=0.1000 0000 0000 0000 0000 000. What is this number in decimal
Convert the first-order Butterworth low-pass prototype, H(z) = 1 / s+1 to a digital IIR filter using impulse invariant method when sampling frequency is 1 Hz.
