FIELD: measurement engineering. ^ SUBSTANCE: device has input pulse former connected in series with pulse oscillator, pulse distributor, pulse counter, register and digital indicators. N frequency doublers connected in series are introduced into the device. Input of first frequency doubler is connected with output of input pulse former. Output of the last frequency doubler is connected with complementing input of pulse counter. Pulse oscillator and pulse distributor both define time of count. Device allows measuring frequency of sinusoidal pulses when the input signal is significantly distorted. ^ EFFECT: high precision of measurement. ^ 1 dwg |
