DEFINITION

Classification: 315/368.23

By multiplying of signal:

(under subclass 368.21) Subject matter wherein the control signal is produced by a circuit which performs multiplication of two signals.

(1) Note. The two signals are often two representations of a single signal.

(2) Note. The signal to be multiplied is often a ramp signal derived from a scanning deflection circuit.
