摘要： This tuning means is provided with a circuit for facilitating manual tuning in electronic-tuning type radio receivers. The tuning means further includes gate circuits (30, 32, 34, 36) which, upon receipt of broadcasting waves, temporarily interrupt a manual tuning command supplied to systems (22, 24) which control bias voltages applied to a variable reactance element (11), and simultaneously deliver AFC voltages.

摘要： An electronically tuned radio receiver adapted for digital selection is provided with circuit means (b9) for detecting that the received frequency is outside a band, and circuits (60, 62, 48, 50) for bringing the received frequency back within the band in response to an output from the circuit means (b9). In changing over bands, these circuits make it possible to avoid the inconvenience of changing the received frequency to a value below the lower frequency limit of a band. Moreover, pulse generator circuits (144, 142) are connected to the strobe terminal G of a multiplexer (46) which changes over selection systems. This circuit is intended to rationalize selection speed.
