Television interference occurs when unwanted signals disrupt the reception of a TV broadcast. This can lead to poor picture quality, distorted sound, or complete loss of the signal. Common sources of interference include electronic devices, such as microwaves and cell phones, as well as physical obstacles like buildings or trees that block the signal. There are different types of interference, including radio frequency interference (RFI) and electromagnetic interference (EMI). RFI is caused by other radio signals, while EMI results from electrical devices emitting noise. Understanding these causes can help improve TV reception and reduce disruptions.
