Oscilloscope Question

  1. Feb 14, 2007 #1
    I overlooked a problem in my lab manual and wasn't able to complete the last problem, I was wondering if anyone would know anything about Oscilloscope:

    What happens when sustained consonants such as "Shhhh" sound on Oscilloscope differ from other consonants or humming/singing?

    The "shhh" sound acts like white noise - multitudes of different frequencies are generated. So no periodic wave will be obseved, while singing and humming might display some periodic disturbances.
