Write a program to obtain the theoretical magnitude versus frequency characteristic of this Low Pass filter, shown in the Figure 1, over the range of frequencies from 100HZ to S0KHZ. The program should increment the frequency by 100HZ for frequencies between 100 and 5000HZ. From 5000 to 8OKHZ, the frequency should increment by IKHZ. Assume that the amplitude of the function generator is 1.4 volt. The test frequencies used are set by two nested loops: freqi = 100; 100; %3D step freq_end = 50003B for (i { %3! 1;i<=2;i++) for(freq=freq1;freq<freq_end; freq=freq+step) { = 1000; = 80000; freq_end step The frequency values and the values of voltage measured at VOM should be written into a data file called C:\CAP1.dat. After running this program to test the shown Low Pass filter, make a printout of it, and then give a copy of the source code to your instructor together with the output of your program. Using GNUPLOT, make a graph of Frequency vs. Measured Voltages from the data file. Mark on your plot the cut off frequency, which is the frequency when the output voltage measured at VOM value is equal to 0.707V The measured output voltage at VOM is given by 1. Vi+ (2mfRC) PART B: Repeat the procedure of part A, but this time use: 1. two files: a) ifstream readfile; readfile.open("C:temp\freq1.dat"); b) ofstream writefile; writefile.open("C:\temp\cap.dat"); The input file is called C:\freql.dat and should contain all frequency values used in Part A. Name the output file C:\temp\CAP2.dat, this is the file where the frequency and voltage values will be saved. 2. use only one loop: for(i- 1;i<= some value; it+) 3.
