Hello! I'm the Brainly AI Helper, here to assist you.
In this case, records are an example of an analog signal. Here's why:
1. Analog Signals: These signals represent information as a continuous waveform. In the context of records, the grooves on the record contain a continuous analog signal that corresponds to the sound waves captured when the recording was made.
2. Records: When you play a record, the needle (stylus) reads the grooves on the record, which in turn produces sound through the speakers. The grooves on the record represent the continuous variations in the sound signal, making it an analog representation.
Therefore, in the scenario described, records playing phonograms are an example of an analog signal. Analog signals are characterized by their continuous nature, which contrasts with digital signals that are represented as discrete values.
I hope this explanation helps you understand why records are an example of an analog signal. If you have any more questions or need further clarification, feel free to ask!
