Hello - I'm working on an updated version of my mixer-preamp-amp and want input/comments on the mixer-preamp stage.
For background, the application is audio input from two computers plus a 3rd aux input, and output to a couple of 6 ohm monitors. This device allows variable mixing of the three...
Please help me, I got problem.
From circuit diagram
Target : I want to make square wave on Vout (Period =18 sec on :8 sec off: 10 sec)
I have problem when I use scope to measure triangle and Vout , I have followed target. But when I use scope to measure Vout only, time Period and time on reduce...
Hi,
i am trying to understand and develop my own simplified version of iepe signal conditioning circuit. however, i have been reading TIDUD62 and following TIDRRP9 documents and couldn't figure out few things as i am not an expert with Op-Amps. i have basic understanding of analog electronics...
Hi People,
I am using an LM 319 High Speed Comparator to produce high frequency square wave as shown. However, from the first diagram, I assembled the connections based on second diagram, it does not work. The V+ and V- that is negative rail and positive rail I used is +9 and -9 V from 2...
I have put together an overly complicated headset tester with hopes to expand it to a intercom station. But it doesn't work as I wish. No mic audio is audible in the headset. I am using a standard aviation headset David Clark H3312 with a 600ohm load.
Have I overlooked something very obvious...
I want to build Colpitts Oscillator Op-amp Circuit from here **broken link removed**
In the schematic it uses classic Op-amp 741 with 2 voltage sources. I have only Op-amp LM358 which using single voltage source.
What changes i need to do to schematic to make it work.
