Signal Processing in Analytical Chemistry

gives rise to a single peak in the frequency domain. In contrast the sharp edges of the square wave in the second example lead to high-frequency components in the FT. The last two examples demonstrate that more slowly varying signals have fewer high frequency components. 3.2 Noise The noise in an analytical signal can be classified in

History of the Development of Ultrasound Technology -

These high-frequency sound waves set the stage for the future development of ultrasonic technology. There were a few discoveries in the late 18th and 19th centuries that aided in this development but Spallanzani’s document was 100 years before there was an actual development that humans could harness and use.

Low-pass filter - Wikipedia

The filter is sometimes called a high-cut filter or treble-cut filter in audio appli ions. A low-pass filter is the complement of a high-pass filter . In optics high-pass and low-pass may have the different meanings depending on whether referring to frequency or wavelength of light since these variables are inversely related.

Remote Sensing Special Issue : Ocean Radar

High-frequency surface wave radar HFSWR plays an important role in wide area monitoring of the marine target and the sea state. However the detection ability of HFSWR is severely limited by the strong clutter and the interference which are difficult to be detected due to many factors such as random occurrence and complex distribution

Accurate ECG Signal Processing

Implementing a high pass filter using hardware. The cut-off frequency should be such that the ECG is undistorted while the baseline wander must be removed. A typical value of the cut-off frequency is 0.05Hz. Since this cut-off frequency is very low this method requires bulky capacitors. In this method two stages of gain are implemented

Bandpass-filter signals - MATLAB bandpass

Create a signal sampled at 1 kHz for 1 second. The signal contains three tones one at 50 Hz another at 150 Hz and a third at 250 Hz. The high-frequency and low-frequency tones both have twice the amplitude of the intermediate tone. The signal is embedded in Gaussian white noise of variance 1/100.

Removal of power-line interference from the ECG: a review of

Modern biomedical amplifiers have a very high common mode rejection ratio. Nevertheless recordings are often contaminated by residual power-line interference. Traditional analogue and digital filters are known to suppress ECG components near to the power-line frequency. Different types of digital notch filters are widely used despite their inherent contradiction: tolerable signal distortion

Risk analysis of high level radioactive waste storage tank

Deviations with high frequency of occurrence. After HAZOP analysis the highest-frequency deviations in the high-level waste storage tank are as follows: Low liquid level caused by evaporation of water in the tank. More acidity caused by evaporation of water in the tank. Less acidity caused by the volatilization of acid in the HLLW.

Pitfalls of Filtering the EEG Signal Sapien Labs

How do you chose a filter for your particular analysis goals? Digital filtering is a common preprocessing step when analyzing EEG data. The typical practice in EEG signal processing is to apply a high-pass filter to filter out slow frequencies less than 0.1 Hz or often even 1 Hz and a low-pass filter to filter out frequencies above 40 or 50 Hz Hz.

Filter signal processing - Wikipedia

In signal processing a filter is a device or process that removes some unwanted components or features from a signal.Filtering is a class of signal processing the defining feature of filters being the complete or partial suppression of some aspect of the signal.

Adaptive Hybrid Control of Vehicle Semiactive Suspension

All three methods have been tested for this problem with the results showing that both the wavelet transform and the EMD 1st order IMF methods have similar accuracy. Due to phase shifting and the difficulty of choosing the upper cut-off frequency the high pass filter method produces inaccurate results and hence is not recommended.

Feature Adaptive Sampling for Scanning Electron Microscopy

A new method for the image acquisition in scanning electron microscopy SEM was introduced. The method used adaptively increased pixel-dwell times to improve the signal-to-noise ratio SNR in

Frequency response - Wikipedia

In high fidelity audio an amplifier requires a frequency response of at least 20–20000 Hz with a tolerance as tight as ±0.1 dB in the mid-range frequencies around 1000 Hz however in telephony a frequency response of 400–4000 Hz with a tolerance of ±1 dB is sufficient for intelligibility of speech.

JPEG Transform Compression - Digital Signal Processing

The second method of compressing the frequency domain is to discard some of the 64 spectral values. As shown by the spectra in Fig. 27-11 nearly all of the signal is contained in the low frequency components. This means the highest frequency components can be eliminated while only degrading the signal a small amount.

If this occurs the vent filter becomes blocked possibly either the filter will rupture or the tank will collapse. There are methods for integrity testing of vent filters in place.

Filtering the surface EMG signal Movement artifact and

the filter’s frequency response where signal energy is attenuated by 3 dB should be set where the amplitude of the noise components surpasses that of the sEMG signal. Consequently it is preferable for the high end of the sEMG frequency spectrum to have a low-pass corner frequency in the range of 400–450 Hz.
