(Spatial sampling) Consider a MIMO system with Lt = Lr = 2 in a channel with M = 10 multipaths. The ith multipath makes an angle of iLlcp with the transmit array and an angle of iLlcp with the receive array where Llcp = 1r/M.
1. Assuming there are nt transmit and nr receive antennas, compute the channel matrix.
2. Compute the channel eigenvalues for nt = nr varying from 4 to 8.
3. Describe the distribution of the eigenvalues.
Consider the best possible heat engine working in air at 25°C. The engine continuously converts heat from a source at 300°C to work, and heat is continuously transferred into the engine at a rate of 100 kJ/s.
An amplifier operates from -5V and +5V balanced power supplies. It provides a 3.2-Vpeak sine across a 150 ohm load when provided with a 0.2-V peak input from which 2.0mA peak is drawn. The average current in each supply is 20mA.
1. prove the distributivity commutativity associativity of convolution sum 2. prove that the absolute summability of impulseresponse is a necessary condition for the BIBO stability of LTE discrete time system
A 1900x10^(-6)F capacitor, intially cahrged to 120V, is discharged by a steady state of 120x10^(-6)A how long does it take to discharge the capacitor to 0V
A capacitor in an RC circuit with R = 5.00 W and C = 6.00 mF is being charged. What is the time required for the capacitor voltage to reach 86.5 percent of its steady-state value
The electric field of a uniform plane wave propagating in lossless isotropic medium is E(x,t) = 60(pi)cos(3 10 t + 4x) ay V/m. The magnetic field at point (0,0,0) when t = 0 is 1A/m. The unit of t is second and the unit of x is meter.
