Second-tier approximation for SIR. Modify the SIR analysis of first tier to include a second tier of interferers and compare the resulting SIR with the one derived for N = 7. Consider all 12 second tier interferers, 6 at distance 2D and 6 at distance √3D. (Use the improved approximations for distances for the first tier only. Assume a path loss exponent of n = 4.)
Determine the response of the system when aunit step is applied at input.

Find the applied voltage of an iron-core transformer if the secondary voltage is 240 v, and Np = 60 with Ns = 720
Consider the analogue cosine signal y(t) = COS(8.8pit). It is sampled using a sampling interval of T = 0.5 sec. What is meant by the term aliasing in regard to signal sampling What is the minimum sample rate that should be used to avoid aliasing
Find the inverse z-transform, x(n), of the following functions by bringing them into a form such that you can look up the inverse z-transform from the tables. This will require some algebraic and /or trigonometric manipulation/calculation.
If an AM signal has an un-modulated carrier voltage Vc=A volts(pk) and a load resistance RL of B ohms. How to calculate the Pc (Carrier Power) If the modulation index is known as m, how to calculate the Sideband Power (Psb)
In a step-down converter, consider all components to be ideal. Let v_0 = V_0 be held constant at 5 V by controlling the switch duty ratio D. Calculate the minimum inductance L required to keep the converter operation
1.5- kW toaster takes roughly 3.5 minutes to heat four slices of bread. Find the cost of operating the toaster once per day for 1 month ( 30 days). Assume energy costs 8.2 cents/ kWh.
Design an open-circuited, shunt stub matching network to match a 125 + j20 ohm load to a 700 MHz, 50ohm generator. Show the lengths of your transmission lines in fractions of a wavelength.
A Whetstone bridge has a strain gage in the lower right leg with a 120 ohm nominal resistance. It is mounted on steel with a Modulus of Elasticity equal to 30x106. The other resistors are equal to 100 ohms. The bridge voltage is 5V.
AC Circit analysis and max power transfer, If the output impedance of a certain driving circuit is 50 Ohm - j10 Ohm, what value of load impedance will result in the maximum power to the load?
