Question 291. Sixteen different levels (symbols) are used to encode binary data. The channel bandwidth is 36 MHz. The maximum channel capacity is

Question 292. A form of digital modulation similar to PSK except the digital information is contained in both the amplitude and the phase of the transmitted carrier.

Question 293. What is the minimum bandwidth required to transmit a 56 kbps binary signal with no noise?

Question 294. It is the next higher level in the FDM hierarchy above the basic message channel and consequently is the first multiplexing step for combining message channels
