This chapter discusses how to measure and identify popcorn noise, the magnitude of popcorn noise as compared to 1/f and broadband noise, and applications that are especially susceptible to popcorn noise.
7.1 Review of 1/f and Broadband Noise
Before looking at popcorn noise, it is useful to review the time domain and statistical representation of broadband and 1/f noise. Both 1/f and broadband noise have Gaussian distributions (see Figures 7.1 and 7.2). Furthermore, these types of noise are consistent and predictable for a given design. Throughout this book, we have learned how to predict noise levels through calculations and simulations. However, these methods cannot be used to measure popcorn noise.
