Answer:
Answer: Program to estimate the power spectral density of the signal
Explanation:
fs= 4000; % Hz sample rate Ts= 1/fs; f0= 500; % Hz sine frequency A= sqrt(2); % V sine amplitude for P= 1 W into 1 ohm. N= 1024; % number of time samples n= 0:N-1; % time index x= A*sin(2*pi*f0*n*Ts) + .1*randn(1,N); % 1 W sinewave + noise
Spectrum in dBW/Hz
nfft= N; window= rectwin(nfft); [pxx,f]= pwelch(x,window,0,nfft,fs); % W/Hz power spectral density PdB_Hz= 10*log10(pxx); % dBW/Hz
Spectrum in dBW/bin
nfft= N; window= rectwin(nfft); [pxx,f]= pwelch(x,window,0,nfft,fs); % W/Hz power spectral density PdB_bin= 10*log10(pxx*fs/nfft); % dBW/bin

Answer:
All the members within a class are by default are private. Private function in a class can access public function within a similar class. Private member formed the implementation of the class and also form the private interface of members within the class.
All the member of class can be access by function inside the class when it is declare as private.
For example:
class test
{
private:
int a; // when test:a is private
public:
test() : a() // a is accessible in test class
}
