The Signal and Noise Analysis of Direct Conversion EHM Transceivers

A direct conversion modulator-demodulator with even harmonic mixers with emphasis on noise analysis is presented. The circuits consist of even harmonic mixers (EHMs) realized with antiparallel diode pairs (APDPs). We evaluate the different levels of I/Q imbalances and DC offsets and use signal space concepts to analyze the bit error rate (BER) of the proposed transceiver using M-ary QAM schemes...

Kinetics analysis of electrophoretic deposition using small signal and large signal modeling, Case study: Nano-Mullite suspension

Having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. Finding a white-box mathematical model for weight vs. time curves of Electrophoretic Deposition (EPD) using large and small signal analysis has been studied thoroughly in the present investigation. Weight-Time curves of nano-Mullite suspension have been tr...

Signal search analysis server

Signal search analysis is a general method to discover and characterize sequence motifs that are positionally correlated with a functional site (e.g. a transcription or translation start site). The method has played an instrumental role in the analysis of eukaryotic promoter elements. The signal search analysis server provides access to four different computer programs as well as to a large num...

Turbulence and Signal Analysis

Turbulence deals with the complex motions in fluid at high velocity and/or involving a large range of length-scales. Turbulence asks then many questions from modeling this complexity to measuring it. In a first part, the description of signals measured in fluid turbulence experiments will be made along with a survey of modern signal processing tools that are adapted to their properties of scali...
