NOTE: The following is a list of course outlines available on the TTi web site. For a complete list of available courses, including course outlines not yet available on-line, see Short Courses Offered

Aliasing Demonstration
- Demonstrates principles of aliasing, spectral folding, and the reduction of aliasing errors with an analog low-pass (anti-alias) filter.
AC-Coupling Demonstration
- Demonstrates the effect of AC-Coupling a sine and square signal with and without offset.
Convolution Demonstration
- Demonstrates the Convolution Process.
dB Calculator
- Calculates magnitude ratios and their equivalent decibels.
Digitizing Error Demonstration
- Demonstrates the effect of digitization of data.
DoF-Chi² Calculator
- Calculates a table of Gaussian-random-calculation reliability as a function of Confidence and Degrees of Freedom.
Filter & Alias Analyzer
- Provides a general alias-protection analysis for a variety of popular analog low-pass filters.
Fourier Transform Demonstration
- Demonstrates the calculations and the resulting filter shape of a single Fourier-Transform filter at 10 waves/buffer.
Interpolation Demonstration
- Demonstrates the use of interpolation/resampling on a tachometer pulse acquired at 100,000 samples/second. The program reconstructs the time history by calculating the number of points requested between the original (acquired) values.
Leakage Demonstration
- Demonstrates leakage of the Fourier-Transform filtering operation and the effect of applying several windows to the input time history.
Non-Linearity Demonstration (formerly Distortion Demonstration)
- Demonstrates the effects of several types of non-linearity on the time history and spectrum of a sine wave.
Polynomial Fit Demonstration
- Demonstrates the fitting of data sets (including calibrations) with Polynomial Curves.
Power Spectral Density Calculator
- A general-purpose Power Spectral Density Design and Calculation Tool.
Pulse-Alias Demonstration
- Demonstrates the effect of undersampling (violating Shannon’s rule) on a Pulse Time History.
Running-Average Filter Demonstration
- Demonstrates the effect on the time history and spectrum of a running-average (convolution) filter.
Shock-Alias Demonstration
- Demonstrates the effect of undersampling (violating Shannon’s rule) on a broadband Pyroshock Time History.
Shock Filter Effects Demonstration
- Demonstrates the effect of low-pass filtering on a high-frequency shock time history and the need for large headroom for shock and other tests that have significant “out-of-band” response.
Shock Saturation & Correction Demonstration
- Demonstrates the effect of saturation of signal and slew rate of out-of-band energy on a high-frequency shock time history and the need for large headroom for shock and other tests that have significant “out-of-band” frequency response.
Sigma Delta ADC Demonstration
- Demonstrates the Sigma-Delta Analog-to-Digital Converter process.
Signal-Sound Demonstration
- Demonstrates audibly and graphically (in time and spectral form) a variety of waveforms.
Sine Sweep System Characterization Program
- Characterizes the in-band-frequency behavior of a data acquisition system.
Spectral Plot Format Demonstration
- Demonstrates the effect of selecting linear or logarithmic frequency scales and linear, logarithmic, or dB magnitude scales on spectral plots.
Square Wave Fourier and Butterworth Filter Demonstration
- Demonstrates the effect of several “perfect” low-pass filters on a square wave.
