Digital broadcast signals are a type of transmission used to send audio and video content over the airwaves. Unlike traditional analog signals, which can degrade and produce static, digital signals provide clearer and more reliable reception. This technology allows for better sound quality and higher resolution images, making it ideal for television and radio broadcasts. These signals are transmitted using various standards, such as DTV (Digital Television) and DAB (Digital Audio Broadcasting). They can be received by compatible devices, including digital TVs and set-top boxes, which decode the signals for viewing or listening. Digital broadcasting also enables additional features like interactive content and multiple channels.
