Small-Signal Bandwidth in a Big-Band Era

Abstract: The popular music of several decades ago required many instruments, hence the name "big band era." Today, bandwidth increase is again a sign of the times. The explosion of Internet usage, network-capable cellular phones (3G, 4G, LTE, and Wi-Fi®), music players, and digital video cameras has expanded consumers' expectations for bandwidth. We are on the cusp of wholesale data transfer to all portable devices. Bandwidth has become king, and we are therefore again in a "big bandwidth era." So, why discuss small-signal bandwidth?
