    Logic gates, pull up/down resistor

    Can you post the rest of the circuit that we can't see? Thanks Adam

    Parts and BOM management

    What we do is generate a script (Mentor Graphics) that exports the parts list for the design into excel, we then save this as a separate parts list onto our system How do you guys work? Adam

    Parts and BOM management

    Hello What software are the guys using to design the PCBs? Can you not have a lib folder on the network which they can all access? Adam

    EP Newsletter

    Yeah nice one Ian, I can see it will be of interest to many. I normally just hang around the new post sections and maybe I miss other things that might have been of interest. Adam

    Noise Reduction in Audio/Video Switching Circuit

    You have connection in and out of your bread board. We need to identify which ones are video and which ones are audio. Adam

    Noise Reduction in Audio/Video Switching Circuit

    It should help yes. But it the connection that are important. Can you post a drawing of your connections?

    Noise Reduction in Audio/Video Switching Circuit

    I think that might be your problem, all those wires with no screening. Adam

    Some pcb questions

    Hello. I have never used Elecrow so I can't comment. The hole size should be between 0.2 mm and 0.4 mm greater than the lead diameter. This is for levels C to A respectively of the IPC standard. Adam

    complex number

    Think about the impedance of a circuit like an RC network for instance. How could we work out the complex impedance without it. You have your real part which is your resistor and the imaginary part which is your reactance. We can then work out the impedance which is complex. Adam

    How a BJT Transistor works (base current version)

    So the original argument was that Ie controls Ic and not Vbe because in the simulation it shows Vbe lagging Ie. I know the reason for this but I wanted to show that with an ideal VCCS the same result can be obtained. So in the simulation there is no way for the current in the source to be...

    Learning schematic capture/layout.

    Hello. Not really I have always had a reason for doing a design. I find without a reason I don't have drive to do it. However some of the more popular designs for beginners seem to be flashing LED circuits, temperature operated switch circuits and light activated circuits. Adam

    Choice of Op-Amps

    My misses whines all the time, how do I convert that to frequency. Is it 1/24h.:) Adam

    Learning schematic capture/layout.

    Hello what about thinking of a simple project that you might want to build and design that. Tell us what ideas and we can help. Adam
