"High speed serial link is now the dominant signal propagation design in various communication, computing and embedded applications. Emulation of such channels is important in signal integrity design and product testing, where full channel simulation is restricted due to the need for protection of intellectual property and frequent channel reconfiguration. This thesis introduces robust lossy material and FIR filter design methods that can be used for channel emulation to provide a solution under these restrictions. Based on the channel characterizations normally obtained in the frequency domain by vector network analysis, different emulation strategies and optimization techniques are utilized to emulate different types of channels. Lossy material overlaid on a microstrip trace can emulate a channel with a smooth loss curve. Likewise, lossy material with an RF FIR filter chip can emulate channel with nonlinear nulls and ripples. The emulation performance is evaluated in the time domain by use of an eye diagram and parameter comparison. During the synthesis of the emulating channel, the physical origins of the channel's time and frequency domain characteristics are analyzed. Furthermore, the hardware realization of the emulation structure is demonstrated with positive examples"--Abstract, page iv.
