Kill Input

this active period, often called a process. Time in seconds equals resistance in megohms, multiplied by capacitance in microfarads.

The Signal Input acts like the Trigger Input; it starts new processes when set to Vcc. Unlike the Trigger, Signal Input will hold the Nv active indefinitely. The RC time-out starts after the Signal Input is turned off or set to GND.

The Kill Input sounds ominous, but it is useful. When connected to GND, the Kill Input bypasses the resistor (R1) and almost instantly drains the capacitor (C1). If the Kill Input is low before the process comes in, then the process simply does not start. The Nv does not pass it on to any other Neurons or circuitry. If the Kill Input goes low while the Nv is active, this truncates the process. So, a low (GND) signal to the Kill Input will either prevent or shorten the process.

Lastly, Time Biasing Inputs change the RC time-out. When connected to ground, a resistor — such as R2 — decreases the total resistance. When connected to Vcc, the two resistors — R1 and R3 — form a voltage divider, which can either lengthen the process or create new processes, depending on the ratio between the two resistors.

Connect the Dots

One Nv does not a Net make. We need to connect them somehow. Let's start by wiring one Nv's output into another's Trigger Input. The total process time-out is the sum of the neurons' time-outs (Figure 2).

With a string of three Nvs, the resulting Net looks like a chain with each neuron forming a link (Figure 3). Because of that, we call this topology a
