FFT (Fast Fourier Transform) Waveform Analysis
Data Acquisition > Software > WinDaq To calculate an FFT (Fast Fourier Transform), just listen. The human ear automatically and involuntarily performs a calculation that takes the intellect years of mathematical education to accomplish. The ear formulates a transform by converting sound—the waves of pressure traveling over time and through the atmosphere—into a spectrum, a Read More
Data Acquisition in Microsoft Excel—How to Import Recorded Data
Data Acquisition > Software > WinDaq > WinDaq/XL In our experience, Microsoft Excel is the most popular application for waveform analysis. Our customers ask about porting waveform data to Excel more so than all other applications combined. In response, DATAQ Instruments’ developed WinDaq/XL to allow users of WinDaq software (both recording and playback software) to Read More
Medical Research using WinDaq
Data Acquisition > Software > WinDaq Data acquisition hardware and software offer unique waveform storage and analysis features particularly useful for medical research applications. WinDaq in tandem with Advanced CODAS analysis software has been applied in a wide range of medical research (MR) applications; a market segment notoriously demanding in both price and performance. An Read More
Electromyogram (EMG) Waveform Analysis Software with Advanced CODAS
Data Acquisition > Software > WinDaq > Advanced CODAS With the advent of data acquisition systems, acquiring data from real-world applications has never been easier, more accurate, or more reliable. Once acquired, the data file can be examined and analyzed just as easily. In some applications, the data requires little or no analysis. Simply reviewing Read More
Casting off with WinDaq Software and the DI-730
Data Acquisition > Voltage > DI-730 Sport fishermen would recognize the product immediately. Though this one was rigged to a metal tub filled with water, most fishermen are used to seeing the product attached to the bow of a bass boat where it allows the skipper to easily and quietly maneuver the boat for a Read More
A Closer Look At Advanced CODAS Software
Data Acquisition > Software > WinDaq > Advanced CODAS Advanced CODAS is a seamless software enhancement to WinDaq Waveform Browser playback and analysis software. Essentially a tool box of analysis functions, Advanced CODAS offers almost limitless flexibility in its approach to waveform analysis. This application note seeks to examine each Advanced CODAS analysis function in Read More
A Closer Look at the Advanced CODAS Peak Capture Algorithm
Data Acquisition > Software > WinDaq > Advanced CODAS Versatile data analysis software package offers automatic detection and convenient reporting of critical cyclic waveform information. Any continuous periodic waveform represents a variety of desirable information, such as the beginning and end points of a cycle, the minimum, maximum, or mean signal values within the cycle, Read More
A Closer Look At The Advanced CODAS Moving Average Algorithm
Data Acquisition > Software > WinDaq > Advanced CODAS Versatile moving average in Advanced CODAS algorithm filters waveform noise, extracts mean, and eliminates baseline drift. The moving average is a simple mathematical technique used primarily to eliminate aberrations and reveal the real trend in a collection of data points. You might be familiar with it Read More
A Closer Look At The WinDaq Derivative Algorithm
Data Acquisition > Software > WinDaq The derivative is a mathematical tool used to obtain the rate of change from any given function. When the function to be differentiated is expressed as an equation, we would apply the appropriate derivative formula to attain the rate of change in a similar equation format. When the function Read More
