What is MPEG? (2004)

Explanation

MPEG stands for Moving Picture Experts Group. MPEG video compression is used in many current and emerging products. It is at the heart of digital television set-top boxes, DSS, HDTV decoders, DVD players, video conferencing, Internet video, and other applications. These applications benefit from video compression in the fact that they may require less storage space for archived video information, less bandwidth for the transmission of the video information from one point to another, or a combination of both.

d.

20 Hz

Answer

c.

Explanation

According to Nyquist Criteria the sampling frequency should be greater or equal to two times the signal frequency to remove the effects of aliasing effect. Here, highest signal frequency component is 20 kHz. So, to receive the correct signal at the receiver end the sampling frequency should be at least twice of it. So, sampling frequency should be 40 kHz.
