Abstract
A control signal-multiplexing circuit for producing various forms of multiplexed control signals from control signals of a plurality of channels. The circuit comprises a multiplexer for selecting control signals of a plurality of channels by scanning and multiplexing the control signals by time division; and a control signal converting circuit which is supplied with output signals from the multiplexer, converts the signals of the respective channels included in the output signals into various forms of control signals, multiplexes the control signals, and sends forth the multiplexed control signals to the corresponding control lines.
Claims16
A control signal-multiplexing circuit which comprises:
- a multiplexer having a multiplexing signal for scanning and multiplexing by time division control signals selected from a plurality of channels to produce a first multiplexed control signal;
- and
- a control signal-converting circuit for receiving said first multiplexed control signal, detecting whether the logic level of the control signals of the respective channels included in said first multiplexed control signal has risen or not, and in the event a rise is detected, generating a second multiplexed control signal formed of a rising pulse, and delivering said second multiplexed control signal to a first control line.
