Suppose part of a frame transmitted using a bit-oriented protocol happens to consist of the bits (shown from left to right in the order in which they are transmitted)
101011011111101101011
00011010111010000111010
(a) Identify the problem with this data.
(b) How would the transmitter fix the problem? (Write down the sequence as it would be transmitted.)
(c) What would the receiver do to the received bit sequence?
A continuous time system, describes by y(t) = 5 Cos (2*pi*20*t+pi/2), is sampled at rate 320 Hz. a) Write the mathematical expression that describes the discrete time (sampled) signal. b) Calculate the value of the discrete signal for n=0 and n=4.
An AC induction motor is rated at 900 rpm, 200V, 60HZ 3-phase. If reduce the motor speed by reducing the line frequency to 20HZ, what should be the line voltage
Plot the steady state torque-speed characteristic for Va = 100V, 60V, and 30V. Calculate the armature voltage to be applied in the steady state at the speed of 1500 rpm when the motor torque load require is 3 Nm.
Show that for wires of identical dimensions but made of different materials, such as copper and aluminum, the resistance is proportional to the resistivity of the material. the resistance of a certain copper wire is 1.5.
Build a series circuit consisting of a 130 V 60 Hz ac source, a 5 ohm resistor, a 53.05 mH inductor, and a 0.33156 mF capacitor. a) Draw the ac circuit diagram b) Sove for the phasor current and phasor voltages across each component.
A 5 KVA 480/120 V single phase transformer is to be used as an autotransformer to transform a 600 V source to a 480 V supply. As a single phase transformer delivering rated load at 0.8 PF Lag its efficiency.
A. Make a two bit counter with The input X =0 makes the counter count from 0-3-1-0 and X=1 goes from 0-1-2-3-0. Choose two different types of flip flops to implement it. B. Describe what will happen on your circuit when the present state is 2 and ..
Perform a link budget for a 25-kilometer point-to-point microwave link in the 30 GHz band. Calculate the free space loss (dB), received power dBm), fade margin (dB), and Fresnel zone radius(m) given the following: Tx Power = 70 dBm
Two slits produce fringes on a screen that is at a distance of 2.05 m from the slits. When the wavelength is 608 nm, the fringTwo slits produce fringes on a screen that is at a distance of 2.05 m from the slits. When the wavelength is 608 nm, the f..
The potentiometer is designed to rotate 330 degrees to give the full range of possible resistance. However, the actual measurement range that is used is only 165 degrees indicating positions of a liquid sensor float ranging from 0 to 10 cm (empty ..
How will the reading of two ammeters compare if they are placed in series in a circuit Will the answer to this question be different if the resistance of the two ammeters is not the same
How is the problem-solving process different when programming in assembly language versus programming in ladder logic?
