9. Calculate the thermal noise or white noise, Noise Power, and Noise Voltage.

 

Calculate the thermal noise or white noise, Noise Power, and Noise Voltage.

// Calculate the thermal noise or white noise, Noise Power, and Noise Voltage.  
K=1.38*10^-23; // Boltzmann's constant
B=10000; // absolute temperature
T=290; // bandwidth

// Thermal or white noise.
N=K*B*T;
disp("Noise =");
disp(N);

// Noise Power
Ndb=-174+10*log10(B);
disp("Noise Power =");
disp(Ndb);

// Noise Voltage of a Noisy resistor. Vn=sqrt(4*R*N); 
// where, R=100. You can change the value of R. 
Vn=sqrt(4*100*N);
disp("Noise Voltage =");
disp(Vn);
// Output

    Thank you for sharing such valuable information. Corporate finance can be challenging because students need to understand investment decisions, financial management, risk assessment, and business strategies. Completing assignments on these topics requires careful research and analytical thinking. I found corporate finance assignment help that provides useful academic guidance. This type of resource can help students understand difficult concepts and prepare well-organised assignments while developing stronger financial knowledge.
