// find voltage gain ,cutoff frequency // Electronic Principles // By Albert Malvino , David Bates // Seventh Edition // The McGraw-Hill Companies // Example 21-2, page 807 clear;clc; close; // Given data R1=220;// in ohms R2=43*10^3;// in ohms C1=100*10^-12;// capacitance in faraday // Calculations Av=-R2/R1;// voltage gain fc=1/(2*%pi*R2*C1);// cutoff frequency in hertz disp(Av,"Voltage gain=") disp("Hertz",fc,"cutoff frequency=") // Result // Voltage gain is -195 // Cutoff frequency is 37 KHertz
