A company stores payment information for their employee working on a project and paid on a project basis, in a text file whose name is entered through keyboard (see a sample input file below). The first line of the file indicates the number of employees and each subsequent line corresponds to information related to an employee payment (employee name, number of hours worked and his/her hourly wage). Write a python program that reads such a file and displays the employees’ names, their hours worked, and their salaries. Finally, it displays the total payment. Your program should consider the following erroneous cases: ● The file does not open/exist

● The format of the data in the file is incorrect (e. g. hours = “1-” or salary = “unkown”)

in which case a RuntimeError exception should be raised and the processing should continue

What is a point-in-time measurement of system performance?

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx, fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx, fs) does automatic scaling and then calls sound(xx, fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
