Question: The following signals are sampled at a fixed sampling rate of 1 kHz. Determine if that sampling frequency is enough to fully reconstruct the waves

The following signals are sampled at a fixed sampling rate of 1 kHz. Determine if that sampling frequency is enough to fully reconstruct the waves using a low-pass filter. If it is not, determine the sampling frequency that would be needed to full reconstruct the waves using a low-pass filter. i. [4 pts] f(t) = cos(2(40)t) cos(2(400)t)
