Please help me answer number 1. Please show a CLEAR and READABLE solution/s. Thanks!!! The course subject is Fundamentals of Electronic Communications.

Problem 2 The noise voltage in an electric circuit is modeled as a Gaussian random variable X with a mean equal to zero (m = 0) and a variance equal to 10-8 (0² = 10-8). a. What is the probability that the value of the noise exceeds 10-4? P(X > 10-4) = ? b. What is the probability that the noise value is between -2 × 10-4 and 10-4? P(−2 × 10-4 < x < 10¯4) = ?

Required information Let X = 4 40° and Y = 20 7. -30°. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The polar form of the quantity (X + Y)X* is . Please report your answer so the magnitude is positive and all angles are in the range of negative 180 degrees to positive 180 degrees.

Kindly answer neatly so that I can understand your writings well. Thanks A carrier with an RMS voltage of 2V and a frequency of 1.5 MHz is modulated by a sine wave with a frequency of 500 Hz and amplitude of 1 Vrms. Write the equation for the resulting signal in its basic and extended form.
