Description
54) УСТРОЙСТВО ДЛЯКОРРЕЛЯЦИОННОГО СРАВНЕНИЯ СИГНАЛОВ54) DEVICE FOR THE CORRELATION COMPARISON OF SIGNALS
(или набор сигналов, форма которого фиксируетс в блоке 7 прин ти решени . Затем на вход возбудител . 3 механических колебаний подаетс анализируемый сигнал, а на вход дополнительного возбудител 5 механических колебаний - эталонный сигнал. Сигналы, образующиес на выходе фотоприемника б, сравниваютс с хран щимис в блоке 7 прин ти решени сигналами, полученными на этапе облучени . В блоке 7 прин ти решени вычисл етс близость распознаваемого сигнала к эталонному по выбранному критерию, учитывающему соотношени частот, амплитуд и фаз гармонических составл ющих исследуемого и эталонного сигналов.(or a set of signals whose shape is fixed in decision block 7. Then, the analyzed signal is fed to the driver's input. 3 mechanical vibrations, and the reference signal to the input of the additional mechanical vibration exciter 5. The signals generated at the output of photodetector b are compared with the stored the signals obtained at the irradiation stage in decision block 7. In decision block 7, the proximity of the recognizable signal to the reference one by the selected criterion, taking into account the ratio of frequencies, amplitudes and az harmonic components of the test and reference signals.
Быстродействие данного устройства на пор док превышает быстродействие известного устройства.The speed of this device is on the order of greater than the speed of the known device.
