AMPLITUDE FILTER Russian patent published in 2000 - IPC

FIELD: automatics, analog computation technology, construction of functional units of analog computers, automatic control means, analog processors. SUBSTANCE: amplitude filter has first and second differential comparators 1₁ and 1₂ which inverting inputs are correspondingly its first and second tuning inputs. Non-inverting inputs are tied up together and form its information input. First and third keys 2₁ and 2₃ are make keys, second and fourth keys 2₂ and 2₄ are break keys. First input of OR-ELSE gate 3 is connected to output of second differential comparator 1₂, its second input is control input of amplitude filter and its output is connected to controlling inputs of third and fourth keys 2₃ and 2₄ which inputs are connected correspondingly to outputs of first and second keys 2₁ and 2₂ and which outputs are tied up together and form output of amplitude filter whose information input is linked to inputs of first and second keys 2₁ and 2₂ which controlling input is connected to output of first differential comparator 1₁. EFFECT: expanded functional capabilities thanks to provision for realization of rejecting or selecting filtration o levels of analog signal without modification of circuit of filter. 7 dwg
