FIELD: computer engineering.
SUBSTANCE: invention refers to the means of specialised calculation equipment and can be used for real-time spectrum analysis of the signals. The technical result is reached due to calculation of real, imaginary part and pulse height of k signal spectrum harmonic. So far as the calculation time is inversely related to maximum tolerance frequency of the input informative signal, then reduction of the processing time leads to increase of maximum tolerance frequency of the input signal. The device contains 2 processors, performing folding the input signal with specific coefficients, and one processor, performing calculation of k spectrum harmonic pulse height. The outputs of the device are informative outputs of the first two processors, real and imaginary parts of k spectrum harmonic in the analog form, and informative outputs of the third processor - k spectrum harmonic pulse height in digital and analog form.
EFFECT: increase of performance and input signal spectrum enhancement due to vectorisation of calculation of real and imaginary parts and introduction of staging.
