Chopper and PWM
Is a chopper a specialized application of Pulse-width modulation? Sylvain Leroux (talk) 10:18, 5 August 2011 (UTC)
 * No, not as a rule. A chopper is a device, while PWM is a modulation method. But there is a connection, you've seen that right. In many applications choppers are controlled by a pulse-width modulated signal. Jaho (talk) 09:45, 16 December 2011 (UTC)
 * What other method would a chopper use, besides PWM? If it's chopping the input to vary the power, isn't that the definition? Amillar (talk) 20:02, 23 January 2013 (UTC)

Chopper Stabilized Driver
 * An entry for "chopper stabilized [stepper] drivers" might be interesting. That is one of the more common uses today. Jbottoms76 (talk) 04:19, 29 July 2012 (UTC)

Query the opening statement that the term "chopper" is much less used nowadays
The word "chopper" is used freely in "Electric Motors and Drives" by Austin Hughes (of the University of Leeds, UK), pub Newnes, 3rd edition 2006.UBJ 43X (talk) 18:12, 3 August 2012 (UTC)

Suggested split
User:Stündle has suggested splitting the section "Chopper amplifiers" into a separate article - I'm inclined to agree (the section is clearly about the amplifier, rather than the circuit), although I'd also consider merging to Amplifier as an alternative. Bring it here for discussion. Yunshui 雲 &zwj; 水  08:38, 4 January 2013 (UTC)


 * Chopper amplifiers are a type of electronic amplifiers. At least today. Further this topic has enough substance for an own article, see de:Chopper-Verstärker.

What is K1 on the schematic?

 * Proof that Wikipedia articles are only written to amuse editors and not to instruct the unknowing. It's a vibrator - a pair of physical electrical contacts opened and closed automatically at some convenient rate, whihc hopefully is described in the linked article. --Wtshymanski (talk) 19:56, 23 January 2023 (UTC)
