What is a Negative, or Positive, Frequency? October 2, 2006Posted by healthyself in Blogroll, Cell phone safety, Definitions, Electrical Wiring, Frequencies, Hz, MHz, Radians, rotation, transmission.
“The concept of negative and positive frequency can be as simple as a wheel rotating one way or the other way. A signed value of frequency indicates both the rate and direction of rotation. The rate is expressed in units such as revolutions (aka cycles) per second (hertz) or radians/second (where 1 cycle corresponds to 2π radians). By convention, a positive frequency is associated with rotation in the counterclockwise direction, whereas a negative frequency represents rotation in the clockwise direction.”
