To understand how common-mode signals are created and then suppressed, you should first understand the interaction of shields and grounds in common cable configurations. The following discussion ...

Differential signal transmission is widely employed in modern electronic systems to maintain signal integrity and high data rates while minimising interference. However, common-mode noise—undesirable ...

Figure 2 shows a typical INA application, where the common mode is at midsupply, and the differential input is in millivolts. Also, note that the reference pin is driven to midsupply. It is important ...

Common-mode rejection is the ability of the differential amplifier (which sits between the oscilloscope and probes as a signal-conditioning preamp) to eliminate the common-mode voltage from the output ...

Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

Signal Transformer has announced its new HCTC series common-mode toroidal chokes for design engineers and manufacturers specifying power supplies accommodating common-mode noise reduction and line ...
