Analog telephones are traditional devices used for voice communication over telephone lines. They convert sound waves into electrical signals, which travel through copper wires to reach the recipient. These phones typically use a rotary dial or push buttons to initiate calls. Unlike digital phones, which use binary data, analog telephones transmit continuous signals. They rely on the Public Switched Telephone Network (PSTN) for connectivity. While newer technologies like VoIP (Voice over Internet Protocol) have become popular, analog telephones are still in use, especially in areas with limited access to modern infrastructure.
