This Module is a prototype or in a concept phase.
Digital modifier
(Superbooth 2024)
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 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).
Technical notes
The module cannot be used for bipolar signals! The negative share of the input signal will be clipped by means of a so-called clipping diode at the input of module A-165-2. This may affect the output circuitry of the module connected to the A-165-2 (depends upon the details of the output circuit and if it is protected against clipping). For the planned field of application that's normally no limitation because these signals (clock, gate, trigger) work usually only with positive voltages.
The module can be used for analog signals only to a limited extend! With analog signals the inputs of the module work as comparators and the negative share of the input signal is clipped (as mentioned above).
