The analog signal given below is sampled at 1200 samples per second. m(t) = 2 sin 120 pt + 3 sin 240 pt + 4 sin 360 pt + 5 sin 480 pt + 6 sin 600 pt + 7 sin 720 pt. The folding (maximum) frequency is __________ .

• 300 Hz
• 360 Hz
• 600 Hz
• 480 Hz

Correct Answer: 600 Hz

Explanation:

Folding frequency (max.) = = 600 Hz.
