H03L1/027 - CPC Classification

Classification description:

Stabilisation of generator output against variations of physical values, e.g. power supply against variations of temperature only by indirect stabilisation, i.e. by generating an electrical correction signal which is a function of the temperature by using frequency conversion means which is variable with temperature, e.g. mixer, frequency divider, pulse add/substract logic circuit
