7/29/08 1 About Frequency, Waveforms, Harmonics, and Power "Frequency" describes the number of times per second that an electrical incident takes place, and is expressed in Hertz (abbreviated Hz). 10 Hz means that a signal changes polarity or pulses 10 times per second.
Pulsed wave (PW) and continuous wave (CW) Doppler instruments generate waveforms that are representative of blood flow movement through arterial vessels. ...
represents 360 degrees. A half wave represents 180 degrees, and a quarter wave represents 90 degrees. If a particular output waveform is delayed one quarter of a waveform with respect to the input waveform, then the circuit under test is said to have a 90-degree lagging phase shift.

Waveforms Abstract Recent interest in the use of timbre changes for the generation of musical structures has raised many questions about how perceived timbres relate to the spectral and envelope components of sounds over time.
