<p>Apparatus for providing a visual indication of electrical signals, e.g. for indicating tuned channels in a TV receiver, includes signal responsive. circuits for respectively energizing corresponding visual indicators, the signal responsive circuits being responsive to respective, mutually sequentially overlapping ranges of the electrical signals, whereby a pair of the visual indicators, preferably also arranged in mutually overlapping relationship, is energized by energizing circuits in response to electrical signals in the region of overlap of the respective ranges, thus reducing the number of indicators required and/or providing a finer indication.</p> |
