FIELD: radio electronics, applicable for improvement of sound quality, improvement of electronic image. SUBSTANCE: one of the variants of the noise suppressor uses at least two components of current-conducting materials of different type interconnected for formation at least of one junction between them; these components serve as suppressor electrodes; the absolute thermoelectromotive force of each current-conducting material of different type forming the junction exceeds 50 μV·K-1 at the activation temperature; these suppressor electrodes serve as leads for connection to the AC circuit. In the second variant of the noise suppressor its electrodes are components formed on the surface, in the third variant the components are made of p-type and n-type semiconductors respectively. Electric circuits may use suppressors both of the second and third variants. In such suppressors the Seebeck and Peltier effects occur simultaneously and the noise arising at an output current close to zero is suppressed. EFFECT: improved design. 28 cl, 20 dwg
