FIGURE 4-23 Connecting up the filter section.

Note that we have continued the GND net from the amplifier actions. I also had to move the GND
supply near pin 4 of IC2 because it was in the way.

The final stage is to connect up the bar-code part of the schematic around IC2. Getting all the nets
between the output pins of IC2 and the LEDs can be a bit tricky. You could, if you prefer, use a bus
for this (see the earlier section in this chapter). The name of the bus needs to be something like
“LEDS:CATHODE[1..10]” to allow the 10 connections to the LED cathodes to be made from IC2.
The bus and direct-connection versions of the schematic are shown in Figures 4-24 and 4-25. On

balance, I think the direct-connection approach is clearer.
