Reconstruction and the Sampling Theorem

The highest frequency component of a continuous-time signal has frequency 199 Hz. Which of the following sampling frequencies will allow the continuous-time signal to be reconstructed from the samples? Select all that apply.

Ideal bandlimited reconstruction of a continuous-time signal from samples can be interpreted as multiplying the FT of the sampled signal by an ideal lowpass filter with passband from $-\pi/T$ to $\pi/T$radians/second.

You have a system that samples signals at intervals of 0.1 seconds. Indicate which of the following signal bandwidths can be sampled without aliasing. Select all that apply.
