Receiver including a station finding circuit

#1. Field of the Invention

#The invention relates to a receiver including a station finding circuit, comprising a tuning information storage circuit constituted as a counter, a counting signal input of said counter being coupled to an output of a pulse generator, a converting circuit being coupled to an output circuit of said counter for converting tuning information present in the counter into wave-range information which can be derived from an output circuit of the converting circuit.

#FIG. 2 shows a block-schematic diagram of a possible embodiment of part of a receiver according to the invention.

#In FIG. 1 a signal originating, for example from an aerial is applied to an input 1 of a tuning section 3 of a receiver. A tuning voltage which is obtained from an output 7 of a tuning information modifying circuit 9 coupled to a number of outputs of a counter 11 is applied to a tuning signal input 5 of the tuning section 3.

#The counter 11 serves as a tuning information store. The tuning information modifying circuit 9 may include, for example, a potentiometer circuit and a gating circuit with which a desired output of the potentiometer circuit can be connected to the output 7 or it may include a digital-to-analog converter. Alternatively, the tuning information modifying circuit may form part of, for example, a frequency synthesizer. In that case a signal originating from an output 15 of the tuning section must be applied to an input 13 thereof so that its frequency or phase can be measured in the tuning information modifying circuit 9.

#Furthermore the counter 11 has an output circuit 17 which is coupled to a converting circuit 19. In the converting circuit 19 the tuning information originating from the counter such as, for example, a frequency or channel number is converted into wave-range information. This is effected with the aid of gating circuits which only supply an output signal when the relevant frequency or channel number corresponds to a certain wave-range. Four outputs 21, 23, 25, 27 associated with an output circuit of the change-over circuit each correspond to one wave-range.
