8 ohm speaker impedance frequency
8 ohm speaker arising from the resonance in the 400Hz, its resistance increased from 8 ohms to 10 ohms, at 10KHz, its resistance began to increase, to 1MHz, 100 ohms. In the absence of the audio signal, the final output is a symmetrical square wave, although speaker impedance of 100 ohms, [...]

Frequency (frequency) is a unit of time to complete the vibration frequency of vibrating object is to describe the amount of reciprocating frequency, commonly used symbols f or v, said in seconds -1. To commemorate the contribution of the German physicist Hertz, people named the Hertz unit of frequency, referred to as “He” is also [...]

The definition of frequency
Unit time to complete the vibration frequency of vibration of objects is described in the frequency of reciprocating motion of the volume, commonly used symbols f or v said that units of seconds -1. To commemorate the contribution of the German physicist Hertz, it is the frequency named Hertz unit, referred to as “Joseph.” Each object has its own nature by the decision had nothing to do with the amplitude of the frequency, called the natural frequency. The frequency of the concept not only in the mechanics, the application of acoustic, electromagnetic and radio technology is also commonly used. Alternating current in the unit time to complete the cyclical changes in the frequency, called the current frequency.
