An acoustic signal is composed of the first three harmonics of a wave of fundamental frequency 454 Hz. If these harmonics are described, in order, by cosine waves with amplitudes of 0.470, 0.840, and 0.860, what is the total amplitude of the signal at time 0.961 seconds? Assume the waves have phase angles θn = 0.

Frequency Analysis Quiz Q1. You have been asked to generate a single signal by summing three different sine waves of equal length (say 5 seconds). The resulting signal is sampled at a rate of 250 Hz. The frequencies of the sinusoidal components are 25 Hz, 40 Hz and 95 Hz. The amplitudes of the signals are 2.0,3.0 and 5.0 units respectively. You have been asked to plot the signal against time. Write the text for a simple m- script that...

12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...
