HI-FI compressor
A part of the Segney NE570 dual compression expander is used together with an external operational amplifier for high input signal compression in high-fidelity systems. When the compander expands at high gain for small signals, in order to prevent overload by a sudden loud signal, clamp diodes D3 and D4 limit the output swing to approximately 7V pp.

The present invention provides a method for controlling the temperature of a flue-cured electronic cigarette and a flue-cured electronic cigarette. The flue-cured electronic cigarette includes an N-section heating body, where N is an integer greater than 1, and the heating body is used for heating tobacco. The method for controlling the temperature of the flue-cured electronic cigarette includes: the flue-cured electronic cigarette heats the i-th heating body, and i is an integer greater than 0 and less than N; after the first preset time, the flue-cured electronic cigarette pairs the i+ The first stage heating body is heated; after the second preset time, the flue-cured electronic cigarette stops heating the i-th stage heating body, and continues to heat the i+1th stage heating body. The technical solution solves the problem of unbalanced smoke output of flue-cured electronic cigarettes during multi-stage heating.The present invention provides a method for controlling the temperature of a flue-cured electronic cigarette and a flue-cured electronic cigarette.
