FREQUENCY METER Russian patent published in 1995 - IPC

FIELD: radar. SUBSTANCE: signal frequency and time delay meter has clock generator 1, pulse counter 2, decoder 3, address counter 4, voltage-to-code converter 5, input signal multiplier 6, complete phase converter 7, complete phase adder 8, modulation signal multiplier 9, modulation index register 10, random frequency calculation unit 11, random phase calculation unit 12, fixed frequency register 15, delay frequency register 16, random frequency multiplier 17, random frequency register 18, random phase multiplier 19, random phase register 20, random phase adder 21, phase adder 22, nonrandom phase adder 23, current phase register 24, fixed frequency adder 25, frequency register 26, time delay multiplier 27, modulation frequency register 28, shifted modulation phase adder 29, modulation phase register 30, modulation phase converter 31, modulation phase adder 32, current modulation phase register 33. Desired effect is attained due to implementing optimal signal processing algorithm enabling noise-immune measurement of fixed frequency and time delay, as well as unknown associated parameters. Meter permanently tracks changes in radio signal parameters and affords utmost measurement accuracy. EFFECT: enlarged functional capabilities. 3 dwg
