If 20 MHz of total spectrum is allocated for a duplex wireless cellular system and each simplex channel has 25 KHz RF bandwidth, find:(a) the number of duplex channels(b) the total number of channels per cell site, if N = 4 cell reuse is used.
a) If accA holds $16 and accB holds $2A, what values will be in the each accumulators after executing the ABA instruction b) What series of instructions would achieve the 16-bit subtraction of $1234 from $8ABC
A long narrow rod has an atomic density of 5*1028 m-3. Each atom has the polarizability of 10-40 F m2. Find the internal electric field when an axial field of 1 V/m is applied.
Important information about System Analysis and Design, Elmwood College Situation: The school is considering a new system that will speed up the registration process.
What is the smallest number of samples that could be collected in order to know for sure whether or not the 1000Hz component is present? Assume you are using a Rectangular window.
A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%.
Operational amplifier - Finding the offset voltage, An operational amplifier has a gain of 20. The input voltage is 125mV and the input bias current is zero.
Assume dual rail logic. Dual rail logic means that both a variable and its complement are available as inputs to the logic block, such that an inverter is not needed to generate B' from B.
Design finite state machine that starts with even number of 1s and followed by odd numbers of 0s. Design finite state machine that starts with odd number of 1s and followed by even numbers of 0s.
How does this cost compare with the current cost of new coal figured generation at 3.5¢/kWh? Write a brief (400 words or less) argument on why Colorado should or should not shut down its coal power plants and replace them with wind farms?
Sketch the complete Nyquist diagram for the following open-loop transfer function. Determine the effect of K on the closed-loop stability. Explain how the "shortcuts" contribute to the diagram.
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.
