Abstract
There are provided an apparatus and a method for detecting a frequency, the apparatus including a signal converting unit removing a high frequency component from an input signal and then converting the input signal into a digital signal, an edge detecting unit detecting an edge of the digital to thereby generate an edge detection signal having a predetermined magnitude, and a frequency estimating unit generating a pulse signal based on the edge detection signal and averaging the pulse signal at a predetermined interval to thereby estimate a frequency of the input signal.

An apparatus for detecting a frequency, the apparatus comprising:
- a signal converting unit removing a high frequency component from an input signal and then converting the input signal into a digital signal;
- an edge detecting unit detecting an edge of the digital signal to thereby generate an edge detection signal having a predetermined magnitude;
- and
- a frequency estimating unit generating a pulse signal based on the edge detection signal and averaging the pulse signal at a predetermined interval to thereby estimate a frequency of the input signal.
A method of detecting a frequency, the method comprising:
- converting an input signal into a digital signal;
- generating an edge detection signal having a predetermined magnitude by detecting an edge of the digital signal;
- and
- estimating a frequency of the input signal by generating a pulse signal based on the edge detection signal and averaging the pulse signal at a predetermined interval.
