The lifetime of a turtle is a continuous value uniformly distributed between 50 and 150 years. Let X and Y be the lifetimes of two randomly chosen turtles, and consider the following events: A = {X < Y } B = {The average of X and Y is less than 100} C = {|X -100| < T }, where T is a fixed number between 0 and 50 (a) Show that events A and B are independent. Include a diagram of the sample space and the events to support your answer. (b) Show that events A and C are independent, regardless of the value of T.
The message signal x(t), in the following system has a nabdwidth of 10kHz. The center frequecy of the Narrow Band Frequency Modulated (NBFM) signal nbfm(f) is 1Mhz, the frequency deviation f1=1khz and the amplitude of the NBFM signal is 1V.
A 3.5inch floppy disc has a nominal capacity of 2 MB. Note that there are eight bits to a byte. Estimate the area of magnetic material allocated to each bit of information. Clearly state any assumption made and carefully note any measured quantiti..
Write down the principle of energy conversion and give an example for single and double excited system.
Using a slotted line, the voltage on a lossless transmission line was found to have a maximum magnitude of 1.5 V and a minimum magnitude of 0.6 V. Find the magnitude of the load's reflection coefficient 'Omega'.
Suppose that an inductor is formed by N turns of a conductive wire wound around a magnetic material. The magnetic material forms a circular cylinder of radius r = 10 cm, and height h = 5 cm. The inductance of the inductor turns of N is defined as:..
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 10 , inductive reactance XL = 20 , and a capacitive reactance XC = 10 . All three components are connected in parallel to the source.
Write C code that senses 3 accelerometer readings into pins PAD 8, 9 and 10 and displays them on the LCD. Also run a timer in seconds and log the values of the accelerometers in 3 arrays every second.
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
suppose we use a 32-bit unsigned fixed-point representation with the binary point to the left of the most-significant bit of the 32-bit number. (We'll have a range of 0 - almost 1.) What is the resolution of this representation
The waveform output by the signal generator in part (b) is changed so that the rectangular pulses have the same width but no longer are periodic. They occur at random intervals of time. Explain in words how the display on the spectrum screen would..
