it is straightforward to calculate the zero-point quantum fluctuations of these mode functions, (uktpkt) = P.(05(k + k') where, on large scales the Power Spectrum P„(k) approaches = r1t.1 3(aH)2 where a is the scale factor during the de-Sitter expansion, and H is the Hubble expansion parameter associated with

ations at the corresponding time (usually dB SPL re: 20 microPascals). (2 pts) Acoustic Waveform (2 pts) EFTA00307625 Amplitude Spectrum, a.k.a. Power Spectrum, Magnitude Spectrum (2 pts) 9. For homework, you drew idealized line amplitude spectra of a pure tone, a complex tone with harmonic and inharmonic
