What is the total amplitude of the signal

Reference no: EM13647049

An acoustic signal is composed of the first three harmonics of awave of fundamental frequency 370 Hz. If these harmonics aredescribed, in order, by cosine waves with amplitudes of 0.16, 0.12,and 0.65, what is the total amplitude of the signal at time 0.616seconds? Assume the waves have phase angles ϑn = 0.
