5.2-1 A compact disc (CD) records audio signals digitally by using PCM. Let the audio signal bandwidth be 15 kHz (a) If the Nyquist samples are uniformly quantized into L binary-coded, determine the number of binary digits required to encode a sample. 65,536 levels and then (b) If the audio signal has average power of O.1 W and peak voltage of I V, find the resulting ratio of signal to quantization noise (SNR) of the uniform quantizer output in part (a) (c) Determine the number of binary digits per second (bit/s) required to encode the audio signal. (d) For practical reasons discussed in the text, signals Nyquist rate. Practical CDs use 44,100 samples per second. If L 65,536, detemine the number of bits per second required to encode the signal and the minimum bandwidth required to transmit the encoded signal. sampled at a rate well above the are

Define the EvenNumber class for representing an even number. The class contains:A data field value of the int type that represents the integer value stored in the object.A no-arg constructor that creates an EvenNumber object for the value 0.A constructor that constructs an EvenNumber object with the specified value.A function named getValue() to return an int value for this object.A function named getNext() to return an EvenNumber object that represents the next even number after the current even number in this object.A function named getPrevious() to return an EvenNumber object that represents the previous even number before the current even number in this object.Draw the UML diagram for the class. Implement the class. Write a test program that creates an EvenNumber object for value 16 and invokes the getNext() and getPrevious() functions to obtain and displays these numbers.A.

3) A steel pin supporting a gondola lift is subjected to an axial stress expected to be 51 ksi with a standard deviation of 3 ksi. The steel has a Sy of 60 ksi and S. of 80 ksi, both with a standard deviation of 5 ksi. Material yielding is considered a failure and will require part replacement. An ultimate failure will result in the loss of 20 human lives. a) If there are 100,000,000 of these parts in service, how many lives would you predict to be lost? b) The cost of this part varies linearly with the cross-sectional area (for the same length part, to double the cross- sectional area requires twice as much steel and twice the cost) The stress experienced by this part varies inversely and linearly with the cross-sectional area (you can imagine part as being in pure tension). By what fraction would you increase the cost of the part?
