<h3>Why knowledge seeking is important?</h3>
Information seeking as a social phenomenon has been instrumental in identifying how academics disseminate new ideas and comment on existing research. Observing how academics make informed choices, and identify resources and strategies to stay on top of the publications is an important element of academic research.
<h3>What are information-seeking Behaviours?</h3>
Information-seeking behavior is the act of actively seeking information to answer a specific query. Information-searching behavior is the conduct which stems from the searcher interacting with the system in question.

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
