Doepfer A-165-2 Digital Modifiers

Module A-165-2 includes six modification circuits for digital signals (clock, gate, trigger, start, stop etc.) which are derived from the two input signals Input 1 und 2:

• inverted signal of Input 1 (labelled 1)
• inverted signal of Input 2 (labelled 2)
• T flipflop (toggle flipflop), controlled by Input 1, this output changes it's state whenever a the rising edge of Input 1 appears (labelled 1/2, as it works similar to a 1:2 frequency divider)
• Set/Reset flipflop, this output changes it's state to "high" during the rising edge of Input 1 and turns "low" during the rising edge of Input 2 (labelled RS)
• inverted output of the Set/Reset flipflop (labelled RS)
• pulse output, during both the rising and falling edge of Input 1 a short trigger pulse with about 50 ms lenght is generated (labelled with the sign ± and a rectangle pulse symbol) 

The outputs 2, 1/2, RS and the pulse output are equipped with LEDs that display the state of the output in question.
The output level for all six outputs can be set to 0/+5V or 0/+11V by means of a jumper or wire on the pc board.

Voltage thresholds for the input voltages:

• voltages below +0,8 V are treated as "low"
• voltages above +3 V are treated as "high"

Typical applications

• starting and/or stopping of events or switching operations with the RS or RS output (e.g. controlled by the trigger outputs of a sequencer, e.g. in combination with electronic switches)
• generation of inverted digital signals
• frequency division (1/2 output)
• generation of short pulses during the rising and falling edge of a digital signal (e.g. triggering an envelope at both rising and falling edge of a gate signal).

• Width: 2hp
