BROADCAST RECEIVING APPARATUS, INTERFERENCE DETECTING APPARATUS AND INTERFERENCE DETECTING METHOD |
摘要 |
<p>To form structure that can remove an adjacent undesired-wave signal such that it is possible to produce a simpler and lower-cost device having the structure. The device includes a front-end unit 2 that converts a signal coming from a target broadcast station into an IF signal, an IF filter 4 that filters the IF signal by using a predetermined bandpass filter and outputs filtered signal, a D/U-ratio output unit 5 that generates a signal indicative of an intensity ratio of a desired-wave signal to a undesired-wave signal from an output signal containing the desired-wave signal and the undesired-wave signal and outputs generated signal, a comparing controlling unit 6 that outputs a comparison result indicative of a comparison of output of the D/U-ratio output unit 5 with a threshold. The D/U-ratio output unit 5 includes an IF limiter that limits attenuation of an input signal.</p> |
