Creating A Balanced Line Output From an unbalanced line level signal Converting Balanced Line Level to Un-Balanced NOTE: The 22K resistors used here work great, but 22K can cause noise to be picked up from close digital tracks (e.g. 3.3V clock signals). We discovered just such a problem on a digital PCB causing pickup to occur […]

Colour Temperature
When a black object such as a piece of iron is heated up it changes colour depending on the temperature that it is heated to. It turns out that this range of colors is very useful for describing the colour tint of white light. You can actually determine the temperature of hot iron by measuring its […]
Comparators General
When Input+ > Input- the output is high. When Input- > Input+ the output is low. Important specifications when choosing a comparator Differential input – just like op-amps don't assume a comparator will operate rail to rail on its inputs, always look for the "differential input", "common-mode input voltage range" or similar rating to see over what range it will accept […]

This app allows you to inspect the contents of any file byte by byte, with each value displayed in hexadecimal and ASCII in a wide window, and hexadecimal, decimal and ASCII in […]
Oscilloscope Probes
The x1 and x10 switch They call it x10, but actually its divide by 10 as the probe has a series resistor in it in x10 mode. The x1 mode switch simply bypasses this series resistor. If you want to know all the details take at look at this excellent video. Probes are normally used […]
Electrolytic Capacitors
Electrolytic Capacitors Life The life of Electrolytic capacitors drops significantly with temperature which is why they are rarely found in automotive applications.
