Location of faults in linear circuits such as amplifiers, and indicates the need for a multimeter. Advantages and disadvantages of analogue and digital meters are explained - provides a design for a simple bench amplifier/signal tracer, with full constructional details and advice on how to use it.
Testing of logic circuits, and after emphasising the need for a logic tester in this work, a design for this item is provided and its use explained.
Component testing and includes circuits for testing operational amplifiers, thyristors and triacs, and FETS. A design for a CMOS tester which can cope with most CMOS ICs is also included.
"Doing it Digital" by John Burton. Includes Block Diagram for the design of a Digital Temperature Controller.
An Introduction to SCART by David Vere. Also known as a Peritel Connector or Euro Connector. It was always there but hardly ever used. Pre-Digital Boxes!
Comments: "What the article doesn't tell you is that you still need the RF lead between the VHS/DVD recorder and the TV, in order to record programmes while you're out. This leads to numerous signal dropouts if you have digital TV or a set top box. It's frustrating to be watching a programme then suddenly be confronted with a blank screen and a notice 'Weak or missing signal'. The aerial lead must go straight to the TV or set top box: routing it via a VHS/DVD recorder seems to weaken the signal: at least this is my experience (in London)".
"Think how much electricity digital boxes use up and the effect on the environment when they generally are left on stand by all through the night."
"Going back a few years ago now when I was into repairing TV sets there was a wild rumour about, that our TV sets consume more electricity when in stand bye than when you are watching them."
