With reference to the triangular speed profile of Figure P18.4, determine the trapezoidal speed profile required to move a load 0.5 m in 3 s.
Explain briefly from what you notice about the digital output values in (a) why a digital output value of an A/D converter is rarely the exact same digital value as the analogue input value.
1.explain what is the instantaneous values of AC AND phase shift angle are. Explain what the effective and average values of AC are. How are they related with amplitude. 2.Draw a calculated conductivities triangle for the circuit with a parallel co..
Determine the maximum bit rate for an FSK signal with a mark frequency of 48Khz, a space frequency of 52Khz, and an available bandwidth of 10kHz.
An analog system has a bandwidth of 10 MHz, a photodetector of = 0.5 A/W and ID = 1 nA, and a signal to noise ratio (SNR) of 30 dB. The receiver's temperature is 270 C and the load resistance is 50 .
Determine the generator matrix for the coder illustrated in Figure 11.15. Use the generator matrix to generate the complete set of code words and use the results to check the code words shown in Figure 11.15. Show that these code words constitute ..
a signal franging from 1khz to 100khz will be put into a davice that will need amplification that will output to speakers. A 12v battery is available as a power source, however the current out of the battery should be kept to a minimum.
Given: A permanent magnet DC motor with kv = 0.7 v-s is tested under the following two conditions: Test 1: Apply 120 V; motor unloaded, Ia=2A and w=160 rad/s Test 2: Apply 120 V, increase load torque until Ia=6A and w=137.1 rad/s
The resistance of the coil is .4 ohm. The inductance of the coil is 2.4e-4 H. The rotor inertia is 2.0e-5 kg m2. The current to torque gain is 0.06 Nm/A. The friction torque is 0.18 Nm. A 12 V voltage source is applied to the motor.
Are these results from a sample survey or an experiment? Why?
A source connected to the primary winding supplies an impedance load connected to the secondary winding. The load absorbs 15 kVA at 0.8 p.f. lagging when the load voltage is 118 V. Assume that the transformer is ideal and calculate the following
1. The PowerPC 601 processor addresses a maximum of 2^(32) bytes of memory. What is the maximum number of 64-bit words that can be stored in this memory. 2. A certain IBM 970 processor has a system clock frequency of 1.2 GHz, what is the clock peri..
