FourierScope

FourierScope FourierScope is a program for constructing radio signals and their spectral analysis. The program is designed for students of radio engineering specialties and all who are interested in the spectral analysis of signals and is intended primarily for training and familiarization with the spectra of signals most commonly used in theoretical and practical radio engineering. FourierScope replaces the whole complex of radio instruments: Signal Generator, Modulator, Oscilloscope and Spectrograph. The program editor allows the simulation of signals, both simple geometric shapes and those represented by complex functions, as well as the application of modulation to them. By means of the fast Fourier transform the program obtains Frequency, Phase and Energy spectra of the signal under study. The graphical construction of signals by points allows to quickly and clearly simulate the desired signals. Bezier curves and arbitrary function sections can be used in signal construction, which enriches the simulation capabilities of real signals. A formula editor allows input of a wide variety of functions of any complexity. Recognizes notations of basic logarithmic and trigonometric functions. Spectral analysis finds amplitude, phase, and energy spectra. Spectral analysis is done with a special algorithm, allowing you to quickly and accurately find the spectra of signals. It is possible to apply one of the modulation types to the original signal (amplitude, frequency, phase). And also a variety of Balance Amplitude Modulation (BAM) and Broadcast Signal Spectrum Extension (SSB). Adjustable accuracy in function playback and Bezier curves. Easy-to-use editor to plot the signal and view spectral characteristics.
