Abstract
An experimental method to measure the reflection functions for discontinuities in cylindroconical waveguides is presented. It involves a single discontinuity and uses a pulselike incident signal. FIR techniques are used to design the incident signal and signal processing is made in the time domain. Two methods to stabilize the numerical deconvolution are considered, those based on singular value decomposition, and the conjugated gradient method. Results presented are related to taper discontinuities, but the method can be applied to other discontinuities as well.
