Analog broadcast signals are a type of transmission used to send audio and video content over the airwaves. These signals vary continuously in amplitude or frequency, allowing for the representation of sound and images. Traditional television and radio broadcasts often relied on analog signals before the transition to digital formats. The main advantage of analog signals is their simplicity and ease of reception with basic equipment, such as radio receivers and television sets. However, they are more susceptible to interference and signal degradation compared to digital signals, which can lead to a loss in quality during transmission.
