Telecommunications engineering focuses on the Transmission of Information across a Channel such as a Coax Cable , Optical Fibre or Free Space . Transmissions across free space require information to be encoded in a Carrier Wave in order to shift the information to a Carrier Frequency suitable for transmission, this is known as Modulation . Popular analog modulation techniques include Amplitude Modulation and Frequency Modulation . The choice of modulation affects the cost and performance of a system and these two factors must be balanced carefully by the engineer. Once the transmission characteristics of a system are determined, telecommunication engineers design the Transmitters and Receivers needed for such systems. These two are sometimes combined to form a two-way communication device known as a Transceiver . A key consideration in the design of transmitters is their Power Consumption as this is closely related to their Signal Strength . If the signal strength of a transmitter is insufficient the signal's information will be corrupted by Noise . SEE ALSO |
