'Is a resistor necessary?'
« on: 14 Feb 2019, 19:48:56 »
Today in my email, a question about the need to use a resistor in a discriminator output. My reply:

Is safe sex necessary?  ;)

https://www.discriminator.nl/faq/index-en.html - 'Discriminator Outputs', Question 6 -

'What's the function of the resistor?

Connecting or disconnecting an interface to the discriminator output might cause a short-circuit. The limiting resistor prevents the discriminator IC from being loaded or damaged. Further to that, it prevents your PC's microphone or line input from being overloaded.'
