In this chapter, you will review and implement some important techniques for digital signal processing and data transmission. In particular, you will learn about the Fast Fourier Transform (FFT) and build a spectrum analyzer using the FFT. A technique called Orthogonal Frequency Division Multiplexing (OFDM) has become very popular for broadband wireline and wireless data transmission. OFDM uses an inverse FFT for modulation and an FFT for demodulation. Therefore, it is important for people specializing in communications and signal processing to have a strong understanding of the FFT. OFDM is the subject of Chapter 17
