Answer #1

ANSWERS -

1A. Increase bitrate

Increasing bitrates increases the audio quality keeping other parameters like frequency and sample rate constant.

1B. Parity bit for error detection

Parity checking is one of the types of error detection in networking.

1C. Simplify overall design complexity

Don't care condition in Kmaps helps to simplify the complexity also the output boolean expression.

1D. Memory

Hard drives belongs to RAM which is part of memory unit in Von Neumann Architecture.

1E. Ability to reuse designed components

Its not an advantage of hierarchical design.
