Question

Visual studio C++ Thank u Problem Statement: components needed for a given cutoff You are to create a program that can be used to find the (f) and frequency for a Sallen-Key Low Pass filter A user will enter the values for the cutoff frequency (o to user will then have the options of having a table created showing the frequency response user's decision) or entering another fe and C1 exiting. The Sallen-Key Low Pass Filter Circuit (Unity Gain) is modeled below: Min O Win WW C1 The needed equations for the components are (given C1 and fe): 4.0 atan(1.0) Q 0.7071 C2 C1 2 R1 R2 The equation to use for the frequency response (gain) table: G An example of the first input screen: visual studio 2010WProjectslFinal.Part.BADebug Final Part B exe nicrof arads lease enter the value for Please enter the cutoff frequency, fc. in Hz: 10000 Farads value for C1 is: B.01A nicro B. R120 microfarads for i value R1 and R2 is: 1125.395 ohns The value for 100B0.000 Hertz he cutoff frequency, fc is any key to continue Press An example of a simple menu visual studio 2010WProjectslFinal.Part BMDebugWFinal.Part.B.exe lease choose front Enter in neu values for R and Create the freq response table when fc 10000.000 exit the program. Using a table, show the frequency response between 0 and a value the user decides in 1kHz increments. Your output should be similar to:
