A CMOS RF RMS Detector for
This project involves the design of a CMOS RF RMS Detector that converts the RMS voltage amplitude of an RF signal to a DC voltage. Its high input impedance and small area make it suitable for the built-in-testing of critical RF blocks of a transceiver such as a Low Noise Amplifier (LNA) and Power amplifier (PA) without affecting their performance and with minimum area overhead. DESCRIPTION: Th...
متن کاملMorphological Detector for Multilevel Signals in - Noise
The novel approach was developed for multilevel signal detection in channels with impulsive nonGaussian noise. This approach consists of using morphological nonlinear image filtration principles for two dimensional signals. It is a new method of signal demodulation, using three dimensional image processing algorithms. Successful results of this morphologic detector encourage more investigation ...
متن کاملOptimal Detection of Multiharmonic Visually Evoked Potentials
We consider the problem of detecting visual evoked potentials (VEP's). A matched subspace lter is applied to the detection of the VEP and is demonstrated to perform better than a number of other evoked potential (EP) detectors. Unlike single-harmonic detectors, the MSF detector is suitable for detecting multi-harmonic VEP's. Moreover, the MSF is optimal in the uniformly most powerful (UMP) sens...
متن کاملComparison of RMS Value Measurement Algorithms of Non-coherent Sampled Signals
ODAY, high resolution analog to digital converters (ADC) are often used for precision measurements of voltage and current. The measurement uncertainty of the RMS value of the analog sinusoidal signal depends on the quality of the ADC and on the algorithms used for RMS estimation. This paper will focus only on the algorithms for RMS estimation of the sinusoidal signal. The comparison of classica...
متن کاملThe Tone Height of Multiharmonic Sounds
Multiharmonic tones containing resolved harmonics (1-7) of a fundamental, unresolved harmonics (8-24) of a fundamental, or both resolved and unresolved harmonics (1-24) were presented to listeners at each of six octaves ranging from 32 to 1024 Hz. There also were modified versions of each stimulus in which alternate harmonics were either attenuated or phase shifted. Listeners were asked to judg...
