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?
Briefly discuss the impact of electron energy, electron current and target on the Bremsstrahlung generated.
The river estuary is tidal causing the surface level of the water to rise and fall. At certain times of day, reflections from the water surface cause deep fading of the received signal.
a. The mass of an electric car is 900 kg including the passengers. A single motor mounted on the front wheels drives the car, and the radius of the wheel is 0.3 m. The car is going downhill at a speed of 50 km/hr, and the slope of the hill is 30 d..
This document is shown a paper on Orthogonal frequency-division multiplexing with advantages, disadvantages and uses.
design a regulated poewr supply with these specs Output a dc voltage of 10 V Load Variation: 0.3 -10000ohms Ripple Factor: less 0.1% for 2000ohms load
A signal x[n] is formed by sampling a signal x(t) = -4sin(200*pi*t) at a sampling rate of 400Hz. Graph x[n] over 10 fundamental periods versus discrete time. Then do the same for the sampling frequencies of 60 and 200Hz.
Find the imaginary part of e^ - (j pi)/2 Find the magnitude of e^ jtheta (for any real value of theta) Find the magnitude of Ae^( j theta) (for any real values of A and theta) Find the phase of -5j in radians
A dc series motor has a armature current of 10A at full load. The motor terminal voltage is 300V. The armature and field resistances are 2 ohm and 3 ohm respecitively. The motor speed at full load is 250 rpm. Calculate the starting torque of the m..
A 1cmx2cm rectangular wire loop carries a current of 2A. What is the magnetic field at the center of the rectangle
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
A 300 W resistor is connected across the 300 Wantenna input of a television receiver. The bandwidth of the receiver is 6 MHz, and the resistor is at room temperature (20oC). Find the noise power and noise voltage applied to the receiver input.
Suppose station A and B are interconnected through two parallel unreliable links, where each link has a failure probability of 0.1. Calculate the average seconds per day when A and B lose communication.
