Channel selection data memory device
 A channel selection data memory device includes a memory which allows pulse duty data for channel selection corresponding to channels to be read from and written into the memory, a position designating device for designating a given address in the memory which produces an address signal and a write signal when it is operated, a mode selection device for selecting a write mode or a read mode, a tuning pulse generating device which produces a pulse with a duty corresponding to the channel selection pulse duty data read out from the memory in the read mode and sets channel selection pulse duty data with a pulse duty corresponding to the channel to be stored in the write mode, and a write signal supply circuit for supplying the write signal generated by the position designating device when it is operated to the memory.
