About Frequency, Waveforms, Harmonics, and Power "Frequency ...

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.

Peripheral Arterial Doppler Waveform Descriptors: Absent ...

Pulsed wave (PW) and continuous wave (CW) Doppler instruments generate waveforms that are representative of blood flow movement through arterial vessels. ...
