clc
clear all
close all
t = 0 : 0.005 : 0.5; %Time
% Define the voltage source which is effected by Gaussian Noise
Vs = 10;
Vsn=awgn(Vs,20); %Noise is in dbW awgn(input,snr)
C = 10e-6; %Capacitor
R = 5e3;
tau = R*C;
V01 = Vs * ( 1 - exp(-t/tau) ); %RC response of input signal
V0 = Vsn * ( 1 - exp(-t/tau) ); %RC response for AWGN effected signal
plot(t, V01,'r',t, V0,'-+')

You create a plot of voltage (in V) vs. time (in s) for an RC circuit as the capacitor is charging, where V=V_{0} \cdot \left(1- e^{ \frac{-\left(t\right)}{RC} } \right). You curve fit the data using the inverse exponent function Y=A \cdot \left(1- e^{-\left(Cx\right)} \right)+B and LoggerPro gives the following values for A, B, and C. A = 4.611 ± 0.4211 B = 0.1599 ± 0.007211 C = 1.951 ± 0.2051 What is the time constant and its uncertainty? NEED CORRECT...

Write a MATLAB function and test bench script code to solve the above simple RL/RC circuits by following the instructions noted below. The input signal and impulse response generation should be done in the function. The test bench script should be used only to call the function and for signal plotting purposes. No plotting should be done inside the function itself. Name your function L2_C Instructions: Input voltage ,x(t), can be AC or DC. Consider a variable ‘w1’ which can...

An RC-circuit is grounded at its batteryâ s negative terminal. This is the sequence of circuit elements: positive terminal of battery to resistor to capacitor to negative terminal of battery. The batteryâ s emf is 7.453 volts. The resistance of the circuit is 3.2 ohms. Its relaxation time is 23.8 milliseconds. At a particular time, t, the charge on the positive side of the capacitor is 21.2 millicoulombs. Before continuing, carefully calculate that current that runs through the circuit at...

I have already written a MATLAB code to filter noise from a particular audio file however the resulted audio is not playing I use this code snippet: presult = audioplayer(fOut, fs); presult.play; the fout is fOut = filter(b, a, f); I do not know what i am doing wrong as the output playing is still the initial sound not thr noise filtered one. Please help deadline is due in hours. Thanks in advance
