This article describes the principium of line scan revise winding used in the line scan circuit of TV receiver and display, and the requirement for the characteristics of the ferrite core.

The rectifier loop is an important part of the LIA transport system.

This papcr gives a method of nonlinear transformation of signals based on neural network to make nonlinear correction.

This paper discusses the polarity of feedback in the linear correction circuits for vertical scan in TV, proposes a general method for vertical linear adjustment and some points to which attention ought to be paid.

This paper introduces the basic principle to correct the photometric linearity with optical superposition method,and its measuring method;Error equation of linearity correction is given;we also analyze the method of reducing by half multi serial high accuracy linearity correction and the interdependence of quantitative computation.

MST-88 multichannel temperature data logger, with the integrated circuit AD590 as temperature sensor and pocket computer PC-1500(A) as the data process system, can collect 10 field temperature parameters and perform linearity correction automatically.

The linearity correction circuit of positive feedback can make the output voltage be linear with the temperature, so the measurement accuracy of the system is improved.
