What is a Negative, or Positive, Frequency? October 2, 2006

“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.”
