Answer
Using a good circuit board PCB design and shielding techniques
Explanation
EMI is a disruptive electromagnetic energy that is released by one portion of the circuit and reaches other parts of the circuit via conducted or radiated parts.The energy can affect circuit performance or even damage brain cells when high.It is possible to reduce this effect by employing the method of shielding and ground planes to prevent interference with wireless system operations.
Answer: B (130)
Explanation:
A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.
