Electronics penetrating into all areas of technology in the last decade is growing and developing on the basis of the use of synthesized crystals and minerals, which especially applies to the newest direction of this field - laser technology. ...

Reference resonance schemes are promising in the construction of energy-efficient electro-optical discrete light control systems. These systems can find application in light signaling boards at mining enterprises. The most interesting are the schemes of programmed formation of bipolar pulses on the principles of reference resonance. For research of control principles at formation of such pulses, estimation of complexity in relation to key circuits with active resistors, determination of deviations of formed pulses from rectangular form the layout on transistors MP-42B was developed...
