Find the Eb/no ratio in dB for a system operating at 10Mbps in a BW of 1MHz. the un-modulated carrier power is 0.1pW and the system noise temperature is 120 degrees Kelvin.
At the instant shown, car A has a speed of 20km/h, which isbeing increased at a rate of 300km/h2 as the car entersan expressway. At the same instant, car B is decelerating at250 km/h2 while traveling forward at 100 km/h.
Assume R1 = 1 M-ohm, R2 = 3 M-ohm, and C = 1.5 F. Also take the initial voltage across the capacitance to be VC(0) = 4 V. The voltage source VS has a voltage of 9 etV. The switch is closed at time t=0.
A wire is bent in the form of a half loop of radius a = 10 mm and charged with a line charge density XL = 10-9 C/m. Calculate the field intensity at center of the loop.
For a circuit we would like to implement, there are two control signals: x and y. If xy = 01, an 8-bit value R is incremented by 1 and control goes to a second state. If xy = 10, R is cleared to zero and control goes from the initial state to a th..
A 20-hp, 250 V shunt-DC motor has an armature circuit of 0.22 ohms and a field resistance of 170 ohms . At a low-load, the speed is 1200 rpm and the armature current is 3 A. At full-load, the current is 55 A, and the flux is reduced by 6%
For a face centered cubic, the volume of a conventional unit cell is a^3 Find the volume of a fcc primitive unit cell with three basis vectors: (0,0,0 --> a/2,0,a/2) and (0,0,0 --> a/2,a/2,0), and (0,0,0 --> 0,a/2,a/2)
A light comes on in a storeroom when either (or both) of two doors is open. 1. What logic function is most suitable for this operation 2. Draw a circuit to represent each function using a logic gate
A buck-boost converter works with an input voltage of 12 V and switching frequency 10 kHz. The load resistance of 24 Ω requires doubled input voltage. The inductor and capacitors are 1 mH and 100 μF, respectively.
Carlos runs with velocity v=(5.0 m/s, 25 degrees north of east) for 10 min. How far north of his starting position does Carlos finish
An 8cm diameter hydraulic cylinder has a 4cm diameter rod. If the cylinder receives flow at 100Lpm and 12MPa, find the a) Extension and retraction speeds b) Extension and retraction load-carrying capacities
1. What is the effect of sampling at a higher rate on the error performance of a digital modulation scheme 2. Suppose 16QAM was the modulation scheme used for this lab; would the error performance
You are asked by your supervisor to witness factory tests to be performed on 15 single-phase transformers that your company plans to purchase. The 15 single-phase transformers will be used to make five three-phase banks.
