An infinite sheet of surface current density given by (equation 1) A/m exists on a plane defined by x=1. A second infinite sheet of surface current density given by (equation 2) is on the plane defined by x = -2. What is the magnetic field intensity H for any point where x < -2?
equation 1 - Js1 = 10y^ A/m read as Js1(vector) = 10 times y hat (vector)
equation 2 - Js2 = 15z^ A/m read as Js2 (vector) = 15 times z hat (vector)
An OFDM system employs 260 data subcarriers, 40 pilot subcarriers, and 34 guard subcarriers to transmit data through a wireless channel. QPSK modulation is employed for each subcarrier.

If a silicon diffusion is doped with phosphorus (donors) at a concentration of 0.6 x 10^17/cm^3, what is the concentration of holes in this piece of silicon per cm^3 Assume ni = 1.45 x 10^10/cm^3, n = 1000 cm^2/V-s, p = 400 cm^2/V-s
A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load.
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
The following heat engines produce power of 95,000 kW. Determine in each case the rates at which heat is absorbed from the hot reservoir and discarded to the cold reservoir. A Carnot engine operates between heat reservoirs at 750 K and 300 K.
Apple A5 die size is 122mm^2 when fabricated in 45nm technology. Assume they purchase 300mm wafers at a foundry for $ 2.5K /wafer. Assume a yield of 70%. What is Apple's approximate die cost?
