Patent ID: 8249516

Claim:
An apparatus for automatically separating and detecting noise radio waves, the apparatus comprising: bidirectional amplifying means that detects noise signals having amplitude exceeding a set threshold value from the noise signals extracted from radio waves having a specific frequency, records the noise signals or counts the noise signals, and applies received high-frequency radio waves and obtains output signals of two systems having inverted phases; amplitude adjusting means that adjusts amplitudes of the signals of the two systems obtained by the bidirectional amplifying means; and signal synthesizing means that adds the signals of the two systems after the amplitude adjustment and obtains a synthesized output signal, wherein the signal synthesizing means cancels the input signals to become an output having almost zero amplitude, regardless of whether the input signals are modulated with a low frequency, differentiates a frequency characteristic of the signal of one system of the two systems from a frequency characteristic of the other system, makes the noise radio waves at the side of a frequency higher than frequencies of the high-frequency radio waves remain without being canceled, and extracts the noise radio waves.
