Noise canceller as well as high-frequency receiver and portable device each using the same |
摘要 |
A noise canceller of this invention includes a pickup antenna arranged in proximity to a noise signal generation source to extract a noise signal generated by the noise signal generation source, and a noise cancellation unit having a first input for receiving a television signal from a television signal receiving antenna and a second input for receiving the noise signal extracted by the pickup antenna. Herein, the noise cancellation unit removes a noise signal fed from the television signal receiving antenna. Thus, the noise canceller prevents degradation in television signal reception sensitivity due to the noise signal generated by the noise signal generation source.
