The transmitted signal jumps from band to band at a predetermined rate
Dividing the transmitted signal into separate frequency bands that each carry a different data stream✓Respuesta correcta
The transmitted signal is divided into packets of information
Two or more information streams are merged into a digital combiner, which then pulse position modulates the transmitter
Explicación
Frequency division multiplexing gives each data stream its own slice of the channel spectrum, so all streams are transmitted at the same time on different frequencies and are separated at the receiver by filtering. Sharing by time slots is time division multiplexing, and moving between frequencies on a schedule is frequency hopping.
