Figure Captions

• Figure 1 A low pass R-C filter. The 3db frequency cutoff is at $f = 1/(2 \pi R C)$.

• Figure 2 The reference chirp signal. The diamonds are the locations of the 128Hz samples.

• Figure 3 The sampled and reconstructed signal. The dashed line shows the reference signal without the carrier, this what is to be reconstructed. The diamonds show the 6.4 Hz samples which were obtained by mixing, filtering and subsampling the reference signal (figure 2). The pluses show the signal reconstruction obtained by applying the uniform sampling theorem to the sampled data.
