  Basic elements of Communication System Information Source: The term "information source" refers to the origin or starting point of information that needs to be conveyed to a recipient or receiver. It represents the entity or process that generates the data or messages to be communicated. The information source is a fundamental concept in communication theory and plays a crucial role in the overall communication process. Input Transducer: An input transducer, often simply referred to as a transducer, is a device or component that converts one form of energy or physical quantity into another. In the context of electronics and instrumentation, input transducers are used to convert physical phenomena, such as temperature, pressure, light, or sound, into electrical signals that can be measured, processed, or transmitted by electronic systems. Transmitter: A transmitter is a key component responsible for transmitting information or data from the source to the communic
