10 Questions
What is the main purpose of using a short-time window in spectrogram representation?
To improve the resolution in frequency analysis
How does a longer window in time affect the frequency resolution in spectrogram representation?
Increases the frequency resolution
What is the trade-off when using a shorter window in time in spectrogram representation?
Reduced frequency resolution
In spectrogram representation, how does a narrowband signal differ from a wideband signal?
Narrowband signals provide better time information
What is the consequence of using a long window in time for spectrogram representation?
Improves the resolution in frequency analysis
How does a short window impact the frequency resolution in spectrogram representation?
Decreases the frequency resolution
Which type of signal, narrowband or wideband, would be preferred for focusing on detailed time information?
Narrowband
In what way does a wider window impact the representation of time events in spectrogram analysis?
Leads to less detailed time information
What happens to the frequency resolution with an increase in window length for spectrogram representation?
Frequency resolution improves
