Question

Does a broadband signal need two channels to send and receive data?

Answer 1

No, a broadband signal does not necessarily need two channels to send and receive data. Broadband refers to the high-speed transmission of data, which can be achieved through various techniques and technologies. Most commonly, broadband signals use a single channel to send and receive data, such as in traditional asymmetric digital subscriber line (ADSL) connections that utilize a telephone line to transmit data. However, there are also broadband technologies that can use multiple channels simultaneously to increase data transfer rates, such as in bonded ADSL or multicarrier technologies. Ultimately, the requirement for one or multiple channels depends on the specific broadband technology being used.
