Figure 4. Sine Function Coefficients The wavelet coefficients are shown in Figure 4. Figure 5. Four Coefficient Reconstruction The inverse transform is taken by retaining the first four coefficients and setting the others equal to zero. Figure 6. Eight Coefficient Reconstruction The inverse transform is taken by retaining the first eight coefficients and setting the others equal to zero. Figure 7. All Coefficients Retained The inverse transform in Figure 8 is the original waveform. The signal is essentially unfiltered.
