Electronic tuning type receiver having a band display and numerical frequency display

In an electronic tuning type receiver including a digitally controlled preset tuning system, in which a digital signal for a band and a channel selection are supplied from a counter means having a plurallity of stages to a digital-to-analog converter so as to obtain a D.C. voltage signal corresponding to said digital signal, said D.C. voltage being applied to a tuning means of said receiver to select a desired frequency band and to tune to a desired channel frequency within said desired frequency band, the improvement comprising:

• first display means responsive to said digital signal for visually displaying the relative position of said channel frequency being received with respect to said desired frequency band;
• voltage-to-frequency means responsive to said D.C. voltage for providing a frequency signal in accordance with said D.C. voltage,
• counter means responsive to said frequency signal for providing a count signal in accordance with said frequency signal, and
• second display means responsive to said count signal for visually displaying numerically the sum total of said frequency of said selected frequency band and said selected channel.
