Wide Range Voltage to Frequency Converter using PSoC3 Microcontroller
This design describes a wide range voltage to frequency converter in a single PSoC chip, which can measure wide range of voltage between 50mV-5000mV and found suitability in sensor applications. This design is implemented in a PSoC3 device IC CY8C3866. The design implements analog and digital user modules: an IDAC, COMPARATOR, PWM, COUNTER, UART and LCD. The comparator gets the analog input fro...
متن کاملImproved Single Frequency Estimation with Wide Acquisition Range
An improved method for estimating the frequency of a single complex sinusoid in complex additive white Gaussian noise is proposed. The method uses a modified version of the weighted linear predictor to achieve optimal accuracy at low/moderate SNR while retaining its speed and wide acquisition range. Consequently, it has an advantage over known methods that use the weighted phase averager since ...
متن کاملModelling of wide frequency range silicon microphone for acoustic measurement
This work demonstrates with numerical simulations, the feasibility of a wide frequency range and high pressure level piezoresistive microphone based on MEMS technology. An accurate lumped-element model was used to optimize the microphone dynamic response. Mechanical lumped parameters were extracted from structural finite element method (FEM) simulations, while squeeze film fluid parameters were...
متن کاملDigital Logic Implementation of Wide-Range Frequency Linear Detector
Digital logic frequency detector whose operation is based on the analog quadricorrelator is presented. Proposed circuit consists of conventional digital logic devices without an alog elements. Therefore, it has superior reliabilities over component drifts or aging effects. Frequency linear discrimination range is ±100% of the reference clock rate. key words: digital frequency detector, quadrico...
متن کاملWide frequency range force ballistocardiogram; its correlation with cardiovascular dynamics.
The ballistocardiograms of young normal subjects as recorded with a wide frequency range technic are described. These records contain high frequency forces not previously described. An analysis of these components in terms of known cardiovascular events strongly suggests that they have definite dynamic significance. In addition, these correlations offer evidence as to the genesis of some forces...
