A binary PAM communication system is used to transmit data over an AWGN channel. The prior probabilities for the bits bn are P[bn= 1] = 1/3 and P[bn= 0] = 2/3.(a) Determine the optimum threshold (to be compared with the demodulator output) at the detector.(b) Determine the average probability of error.(c) Evaluate the average probability of error when Eb = 1 and N0 = 0.1
If a logic circuit with I_OH = 4.5 V is driving and LED with a 330 ohm limiting resistor, what is the current rating for the LED if the forward voltage drop is 1.8 V
Two metal plates with an area of 4 cm2 and separation distance of 0.01 cm are used to form a capacitance transducer. If the material between the two plates has a dielectric constant of 2.5 and the dielectric constant of free space is 8.85 pF/m
Saturated and unsaturated synchronous reactance, The following readings are taken from the results of an open- and a short-circuit test on a 9375-kVA three-phase Y-connected
Two coupled coils have self-inductances L1 = 50 mH and L2 = 200 mH, and a coefficient of coupling k = 0.5. If coil 2 has 1000 turns, and I1 = 5Sin (400t) (i.e. the phasor current is 5? -90° A). Find the voltage at coil 2 and the flux through coil ..
A silicon diode has a doping profile such that ND = ax3. What is the depth of the junction assuming the p side is uniformly doped with NA per cubic cm. Assume the x origin is at an ideal ohmic contact on the n side of the diode.
explain how to get an output greater than input at the appropriate band (bandwidth, range of frequencies present the highest response) without changing frequency response.
Develop the pseudo-code below for a program that will retrieve 2 bytes (NUM1 and NUM2) from memory, determine which is closest to the numeric value 50, and indicate the result by setting a variable named "CLOSEST" to 1 (if 1st byte is closest) or ..
A 1.1 mF capacitor has initial voltage of 12 V.The energy stored in the capacitor is used to light up a 0.7 KOhm lamp.Assuming that the lamp is completely dimmed when the current through it is less than 0.2 mA, for how long can the capacitor susta..
Two input capture events occur at counts 0xBA47 (first event) and 0x42B3 (second event) of the free-running counter. How many counts have transpired between these two events
An aluminum casting that has a mass of 10 kg sits on a steel surface. How much force will be necessary to get it to start sliding. The static coefficient of friction (mu) for aluminum on steel is 0.61.
Sketching the Dependence of l versus h on Cartesian Axes, The distance l from a point at a height h above the Earth's surface to the horizon can be approximated using Pythagoras theorem by the expression:
