- I have being doing time series analyse of the crab nebula pulsar and cannot come up with a good answer for this question. any help would be greatly appreciated.

The first harmonic is the peak frequency in a power spectrum because it represents the fundamental frequency of the signal. This means that it has the highest amplitude and contributes the most to the overall shape of the signal. Additionally, the first harmonic is the lowest frequency at which the signal repeats itself, making it a prominent feature in the power spectrum.
The first harmonic is significant because it provides information about the fundamental frequency of the signal. This can be useful in identifying patterns and trends in the data, as well as understanding the underlying physical processes that produce the signal.
Yes, other harmonics can be present in a power spectrum. Harmonics refer to frequencies that are integer multiples of the fundamental frequency. In a power spectrum, these harmonics will appear as smaller peaks at frequencies that are multiples of the first harmonic.
The first harmonic is determined by analyzing the frequency components of a signal using a mathematical technique called Fourier analysis. This technique breaks down the signal into its individual frequency components, and the first harmonic is identified as the lowest frequency component with the highest amplitude.
Yes, the first harmonic can change in a power spectrum if the underlying signal changes. For example, if the fundamental frequency of the signal increases or decreases, the first harmonic in the power spectrum will also shift accordingly. Additionally, if new frequency components are introduced to the signal, the first harmonic may change or additional harmonics may appear in the power spectrum.
