a. Above what frequency will the radiated emission of Problem 12.6 begin to fall off as a result of the loop no longer being small?
b. What will be the slope of the fall off?
Problem 12.6
A PCB trace 4 in long and spaced 0.062 in from the return conductor is carrying a 10-MHz, 3.18-ns rise time clock signal. Assume the current in the loop is 50 mA.
a. Determine the radiated field strength in dB μV/m at the fundamental frequency, when measured at a distance of 3 m from the board.
b. Plot the envelope of the radiated emission from 10 to 350 MHz.
c. What is the worst-case margin against the FCC Class B limit, and at what frequency does it occur?

Consider a system for which the output voltage is vout(t) = vin(t) + vin(t - 10^-3). (In other words, the output equals the input plus the input delayed by 1 ms). Given that the input voltage is vin(t) = Vmax*cos(2*pi*f*t),
Design a circuit that satisfies the equation VOUT = 5 * ( VB - VA ). Draw the circuit schematic identifying supply voltages and show your work on component selection.
The wave function of a certain standing wave on a string fixed at both ends is y(x,t) = 0.30 sin(0.0025x)cos(300t) where y and x are in centimetres and t is in seconds. If the string is vibrating in its fifth harmonic, how long is it
