You will perform demodulation of Only ONE message signal among the five described above, which will depend on the last digit of your student ID. Your message signal is determined as mk(t) where k = ( [the last digit of your student ID] mod 5 + 1).
Your demodulator consists of multiplier of carrier signal followed by a low pass filter (LPF). Implement MATLAB codes to realize this demodulation processing; and from this processing, plot the spectrum of the demodulated signal. Compare this with the original spectrum of the message.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
