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
