a. NRZ b. Manchester c. Bipolar AMI d. B8ZS

Which timing and data synchronization method depends upon the data to recover timing.

a. Asynchronous b. Synchronous c. Isochronous d. Plesiochronous

Select the correct statement(s) regarding error correction.

a. error correction techniques can be classified as either error detection or error correction

b. Forward error correction (FEC) depends upon the addition of redundant data bits to correct bit errors during transmission

c. Use of parity bits and Cyclic Redundancy Check (CRC) enables error detection, but not error correction

d. All statements are correct

...is noise caused when the frequency bandwidth of adjacent channels overlap with one another, thus causing distortion on each channel.

a. Thermal noise b. Intermodulation noise c. Cochannel interference d. Impulse noise
