Filed: 1992-02-28
Abstract: PURPOSE:To prevent a click noise, etc., from being outputted in muting operation by substituting data corresponding a DC offset component for digital audio data when output data are put in a mute state. CONSTITUTION:When the muting operation is performed, the offset data outputted by an offset data generating circuit 10 are supplied to a pulse conversion part 6 as a substitute for the digital audio signal obtained at an input terminal 1.

IPC: H04M3/42
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a selective call radio receiver with which whether a mail drop message is new or not can be discriminated at a glance. SOLUTION: Each time a message having a selective call number 1 is received, a timer 13 of the selective call number 1 for mail drop performs count- down from a prescribed set time stored in an ID-ROM 4. When the counted number of the timer 13 becomes zero as a result of its count-down, a time over display flag is changed from '0' to '1'. Thus, it is stored that a mail drop message is received after the elapse of the set time. When reading the mail drop message of flag '1' out of a message storage part 11, the message is displayed on a display part 5 with the attribute such as character inversion or alert.
