Which stage of the transmitter operations involves increasing the signal strength?

The stage of transmitter operations that involves increasing the signal strength is amplification. During this phase, the weak signals generated by the transmitter are enhanced in power to ensure that they can travel long distances without degradation. Amplification is crucial because it prepares the signal for effective transmission through various mediums, whether that be through air or wired connections. A properly amplified signal can withstand interference and maintain quality when reaching the intended receiver, ensuring that the transmitted data remains intact.

Modulation refers to the process of varying a carrier signal in order to transmit information, while transmission is the act of sending the modulated signal out into the medium. Reception pertains to the process of capturing the transmitted signal, which occurs after amplification and transmission have taken place. Understanding the role of amplification helps clarify how effective communication systems can deliver clear signals across distances.
