Efficient Signal Transmission (UMAP)

We describe how digital signals can be transmitted by analog carrier signals. This is the method of pulse code modulation. Transmission by pulse code modulation is widely used thanks to its abilities to withstand corruption by noise and to transmit multiple signals simultaneously. Digital signals can also be used to compress analog signals, thus allowing for more rapid transmission, by employing wavelet series. We shall describe how wavelet series are employed and compare them with Fourier series, showing that in many instances wavelet series provide a better technique.
