Claims

[Scope of utility model registration request]

71 A call sign display device that displays a call sign by receiving frame synchronization data and Hagelpurger encoded data that includes at least call sign data following the frame synchronization data, and detects the supplied frame synchronization data. /- A frame synchronous data detection circuit, a first shift register to which Hagelburger encoded data following the frame synchronous data is supplied; an input switching circuit that directs data to the first shift register; a decoding circuit that cooperates with the first shift register to decode Hagelberger encoded data following frame synchronization data; a second shift register to which data is supplied; a third shift register to which only data pits in the second shift register are supplied; and a data latch circuit to latch call sign data in the third shift register. and a display means for decoding and displaying the output of the data latch circuit, and a fourth shift register into which the call sign data in the third shift register is loaded and output as serial data. Call sign display device.
