Consider a (Nt,Nr) =(4,4) MIMO channel. For the input of the channel x = [x1,x2,x3,x4] assume that each xi is drawn from a BPSK constellation with energy P. Also assume that the channel noise variance is σ2 = 1 From question 1, for the energy levels P = 0.1, 0.5, 1, 5, 10. implement the Zero-Forcing SIC detection method and find the estimate Zzf. is Zzf = x? If no declear an error.
A wafer 100mm in diameter is mounted in an electron-beam evaporation system in which the spherical radius is 40cm. Use Eq. 6.7 to estimate the worst-case varation in film thickness between the center and edges
A panasonic model Rx-ft560 stero uses a 12V_dc powwer supply. At full volume ( max triple min-bass) A max current of 1.4 amps is needed from the power supply. at min volume, this drops to 200mA. (hint: calculate the range of R_L)

Write the VHDL architecture file for a J-K flip-flop that toggles on each falling clock edge. Use J and K for the inputs, Q for the output, and CLK for the clock. All signals are BIT type.
a certain shunt motor armature has a resistance of 0.07 and a current of 50 amperes at 120 volts. determine the counter emf
Consider a symmetrical square wave of 20-V peak to peak, 0 average, and 2-ms period applied to a Miller integrator. Find the value of the time constant CR such that the triangular waveform at the output has a 20-V peak to peak amplitude.
Suppose that a family of logic gates considers the output ranges of [0 - 0.2V] as "0" and [3.1V-3.3V] as "1". What are the reasonable input ranges for "0" and "1"? (a) "0": [0.1 - 0.4V], "1": [2.3V - 3.3V]; (b) "0": [0-0.3V], "1": [2.8V - 3.0V]; (..
A microcontroller manufacturer, Agduino, offers a single product which is produced at two different plants. The first plant located in college station produces 2/3 of the microcontrollers. The remaining microcontrollers come from Austin.
