Implementation and performance evaluation of a broad-band digital harmonic vector voltmeter

Implementation and performance evaluation of a broadband digital harmonic vector voltmeter

A broadband digital harmonic vector voltmeter proposed previously and studied theoretically by the authors was implemented using a special-purpose, random sampling strategy, to avoid the bandwidth limitations due to the finite conversion time of the sample-and-hold and analog-to-digital-conversion (S/H-ADC) devices. The experimental results have shown that the bandwidth of the instrument is not...

A Performance Evaluation and Critique of Singhal Kshemkalyanis Implementation of Vector Clocks

In distributed systems clocks are used for synchronization, ordering etc. Physical clocks which use materials gradually get out of sync over long periods of time called ”clock drift”. Therefore logical clocks are used instead. Lamports scalar clocks offer a very easy implementation of logical clocks however are not strongly consistent. Vector clocks are strongly consistent, but their implementa...

A Novel Implementation for Narrow-Band FIR Digital Filters

In the cascade realization of fixed-point digital filters underdynamic range constraints, the output noise due to accumulation ofroundoff errors is highly dependent upon the order of the sections.For recursive filters it also depends on the pole—zero pairing that formsthe individual second-order sections. The output noise may vary overseveral orders of magnitude for differen...

Comments on “Pattern Characteristics of Harmonic and Intermodulation Products in Broad-Band Active Transmit Arrays”

Active array antenna patterns at harmonic and intermodulation (IM) frequencies have been studied in [1]. In particular, the beam directions have been found at IM and harmonic frequencies for different scenarios. The basic equation, which was used to find the beam directions, is [1, eq. (6)]. However, as a detailed analysis shows, the right-hand side of [1, eq. (6)] is not necessarily zero. A mo...
