  • Characteristics of RC digital filters as bandpass circuits

    Creator:
    Hancock, Robert James
    Abstract:
    One of the most promising methods of constructing bandpass filters without inductors is the RC digital filter. It is simply a number of parallel RC branches which are sequentially switched between the source and the load. If the source signal is at the same frequency as the switching rate of...

  • Variable linear phase digital filters

    Creator:
    Acuna, Fernando R.
    Abstract:
    Linear phase variable filters that are obtained with a frequency transformation of the form cos(ω) = P(cos(W)) were analyzed, where P is a finite degree polynomial, ω is the prototype frequency and W is the transformed filter frequency. A new transformation of third order is proposed. The new variable filter...

  • Design of an asynchronous third-order finite impulse response filter

    Creator:
    Oren, Joel A.
    Abstract:
    With the increased demand for complex digital signal processing systems, real-time signal processing requires higher throughput systems. In the past, the throughput has been increased by increasing the clock rates, but synchronization can become increasingly more difficult. Recently there has been renewed interest in designing asynchronous digital systems. In an...

  • Stochastic properties of morphological filters

    Creator:
    Zhu, Feihong
    Abstract:
    Most of the existing research on mathematical morphology is restricted to the deterministic case. This thesis addresses the void in the results on the stochastic properties of morphological filters. The primary results include analysis of the stochastic properties of morphological operations, such as dilation, erosion, closing and opening. Two unbiased...

  • A DSP controlled resonant active filter for current harmonic mitigation in three-phase power systems

    Creator:
    Ünsal, Abdurrahman
    Abstract:
    Power quality has become an important concern to both electric utilities and end users due to the increased use of non-linear loads in modem power systems over the past decade. Nonlinear loads inject harmonics into the power system and thus may lead to poor power quality and lower power factor....

  • Mathematical morphology : a case study of linear shift-invariant filter implementation

    Creator:
    Eo, Jin-Woo
    Abstract:
    Morphological filters have shown good performance in various image processing applications. Furthermore, their algorithms are easy to implement in special architectures, with the exception that linear filtering cannot be implemented in many of these cases. In this study, a new architecture and corresponding algorithm, capable of realizing linear shiftinvariant filters,...

  • Compensation method of the excess loop delay in continuous-time delta-sigma ADCs based on model matching approach

    Creator:
    Guo, Jia
    Abstract:
    Continues-Time (CT) Delta-Sigma (ΔΣ) Analog-to-Digital Converters (ADCs) have one important constrain, namely the excess loop delay. Most previous excess lop delay compensation methods need to know the exact value of the excess loop delay in advance. However, the value of the excess loop delay is a uniformly distribution random variable....

  • Digitally-programmable switched-current filters

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Digitally-programmable filters have been an ongoing research topic for a number of years. The first such filters were FIR transversal filters using Charge-Coupled Devices (CCD's) and IIR recursive filters using switched-capacitor (SC) techniques. Although both techniques achieve excellent results, they require non-standard and/or additional IC fabrication steps. Low substrate doping...

  • Sensitivity analysis and architectural comparison of narrow-band sharp-transition digital filters

    Creator:

    Abstract:
    Due to advances in high-density low-cost VLSI and communication technology, digital filtering and signal processing are being widely used for real-time signal processing applications. Given the filter specification, choosing the best filter structure for a given application is not a trivial task. The choice of a particular filter structure depends...
