"Scotchlok" connector The "Scotchlok" connector splices two wires together, using asharp metal blade which pierces theinsulation. This is clamped using a pair ofpliers, and covered with a plastic clip.

Use a wire stripper to remove about 1/8in. (3 mm) of insulation from the end of the wire. Lay the bare strands in the inner section of the connector. Use crimping pliers to tighten the two small tongues firmly around the insulated part of the wire. On the other side of the connector, push the wire strands back and down flat. Hold the connector blade upwards to avoid solder running into the spade part.

This prevents the damage to the PCB or components which can occur due to surface stress and splinter when separating the boards. One drawback with this method is that it may leave some unwanted board protrusions on the edges.

If an outlying part of the loom with few wires has been damaged, it may be simpler to replace each wire to the end of the loom instead of inserting a section. If so, use the old, damaged wire as a guide to the length of the new. In an open area of wiring, join old and new with snap connectors.Fitting new wiring Fit a rubber grommet when passing wires through a new hole in the bodywork. When you fit accessories you must use large enough cables. As far as you can, route the new wiring along the course of the existing loom, using the same clips and grommets.

The remaining part joins the separate boards and is then cut with a machine during the depaneling. This helps to reduce the stress on the PCB. One challenge with the V-groove method is that it is restrictive and cannot be used with PCBs that have overhanging components over the edges.

The decoupling capacitors (C4, C5, C6, C7, C9, C10, C11) are arranged around the perimeter of the chip, very close to their respective power pins and to the vias that connect the caps to the internal planes. Notice how the smaller cap is always closer to the power pin; this is because we rely more on the lower-value capacitor for high-frequency bypassing, and thus the first priority is minimizing the inductance and resistance between the smaller cap and the pin.

Before cutting out damaged wires, make sure that the colour coding is the same at each end of the damaged section of each wire, and that it is not so discoloured that it is unrecognisable. If there is any chance of confusion, label both ends.

Since the finite-impulse-response (FIR) filtering is a common operation in DSP, we will continue our discussion based on examining the difference equation of an FIR filter. This simple example will show the typical properties of many DSP algorithms. After reviewing the problem of handling the incoming samples, we will discuss the circular buffering as an efficient solution to the problem.
