What do you mean by band in communication?
how it differs from bandwidth?
Find and draw the Thévenin equivalent of the circuit shown. The load resistor is RL. - Find the load current using your Thévenin equivalent circuit.
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
A 100 hp, 16 pole, 460V, three phase, 60hz induction motor has a slip of 2.4 percent when running at rated conditions. Determine (a) synchronous speed; (b) rotor speed (c) rotor frequency.
Consider a (1;N) SIMO channel (with N > 1), represented by a N x 1 channel vector h1 with hH1 h1 = II h1 II2 = 1. Suppose that the received signal is given by x = h1s + n, where the power of the data signal s is E(IsI2)= P
Examine the impact of the pole offset by executing the program assuming a perfect loop (λ = 0).- How many cycles are slipped by the perfect loop? By how much is the lock time reduced?
A 160-ft-diameter parabolic antenna is driven by a 10-W transmitter at 4.3 GHz. Calculate its effective radiated power (ERP) and its beamwidth.
The number of resistors, their values, and their wattage ratings must be specified. A schematic showing the circuit arrangement and resistor placement must be provided.
What is one very obvious way to reduce delay? On G.711 circuits, the lost packet rate objective is? Name at least two ways to handle the presence of a lost packet ? What is the basic function of a media gateway controller?
The armature resistance is 2Ω. Determine the speed and speed regulation if a load demanding a torque of 50 Nm is connected to the motor. Assume that the losses consist solely of heating of RA and frictional loss torque that is independent of speed..
The input signal consists of an e.m.f. of 60 mV from a source of internal resistance 2.2 kΩ, and the total load on the stage output is 4 kΩ. Determine the current, voltage and power gains of the amplifier stage.
What is meant by a stratified thermal water-storage tank?
Each window is to be 0.6 m in diameter and to be centered 2 m below the surface level. Find the force and location of the force acting on the window.
