assume that the bulk madulus and density of seavater are B= 2.34 x 10^9 N/m^2 and p = kg/m^3. From a point source inside the ocean we generate a sound wave. This wave propagates isotropically (the same in all direction, spherical wave) with frequency of f= Hz. The amplitude of the wave at m from the source of the sound is Sm=m.
a What is the speed of propagation of the sound wave?
b What is the intensity of the sound wave at 10m from the source of sound
c Suppose we now replace this medium (seawater) with air, we keep the same amplitude of the wave at m and the same frequency. What is the intensity of sound wave at m from the source of sound?
Create a state transition diagram for a simple state machine to detect a positive pulse. You choose either a Moore or Mealy machine. Write a Verilog HDL module for your state machine.
A sequence of 10 bits is transmitted over a binary symmetric channel with bit error probability Pe. Assume that bit errors occur independently. The sequence is considered to be received in error if more than two bit errors occur.
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
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.
A common source amplifier utilizes a mosfet for which Va= 12.5 V and is operated at Vov= .25V. What is the value of (gmro) The amplifier feed a load resistance RL= 15Kohms. The designer selects RD=2RL. If its required to realizes an overall voltag..
In the presentation, the presenter, Mr. Rob Tucker discussed three types of disturbance mitigation responses or measures. List the three mitigation types and give a short definition of each of the mitigation type.
Having recently lost her job, Penny Penching is looking for every possible means of cutting costs. She decides that her 4.0-Watt clock radio alarm does not need to be on for 24 hours every day since she only needs it for waking up after her averag..
The output of the FM modulator is sFM(t) = 10cos[400πt + 2πkf] where kf = 10. If the output of the FM modulator is passed through an ideal BPF centered at fc = 2000 with a bandwidth of 62 Hz, determine the power of the frequency components at the ..
The Schussing skier is on 25° slope. His mass is 80 Kg. The Kinetic coefficient of friction between his skis and the snow is μs = 0.08 . His velocity is 9 m/s. a) What is his acceleration in the direction parallel to the slope
draw a gate level schematic of a 4bit ALU that can ADD, Subtract, and AND. include the use of an adder/subtractor unit consisting of 4 full adders, and 4-bit 2:1 mutiplexer. No diagrams, gate level schematic only.
Transmit this data wirelessly to a base station for storage. How much bandwidth would you need.
a) draw a schematic diagram of the network showing all workstations, servers, segments and bridges (or gateways or routers or brouters). b) State which network software is used in the LAN and describe how the software facilitates the functions.
