Claims (1)
で制御し、該ＰＬＬの分周比のデータを記憶する
メモリと該メモリをアドレスするカウンタとを有
し、自動プリセツト機能を持つ受信機において、
前記カウンタがオーバーフローしたときに作動す
るカウンタを別途設けるとともに、該カウンタの
データを受けて作動する表示器を設けることによ
り、受信バンドを一巡して自動プリセツト用に用
意されている前記メモリのエリアの数以上の放送
局が受信されたとき、該メモリにプリセツトされ
なかつた放送局の数を前記表示器に表示するよう
にしたことを特徴とする受信機。 The local oscillation frequency is changed to a phase lock loop (PLL).
In a receiver having an automatic preset function, the receiver has a memory for storing frequency division ratio data of the PLL and a counter for addressing the memory, and has an automatic preset function.
By separately providing a counter that operates when the counter overflows, and by providing a display that operates in response to data from the counter, the area of the memory prepared for automatic presetting can be read by going around the reception band. 1. A receiver according to claim 1, wherein when more than one broadcast station is received, the number of broadcast stations that have not been preset in the memory is displayed on the display.
