    Summing Amplifier Question!

    For E: would it just be: 0000 0001 0010 ... 1111 ? And B: Not sure what formula? C: Would it just be sin(w*f*t) = sin(4000*f*t) so, w*f*t = 4000*f*t and so f = 2000hz?

    BJT Biasing - Simple easy 1 minute answer!

    Yess - Thanks for yalls help though! So, 16.25uA for iB is correct... And from there i can get: ic = (16.25uA) * (beta = 50) = 0.8125mA ANd then Ie = Ib + ic = 0.8287mA And then vce = 8.375V. :]

    These were incorrect? I had Vb = 8V - which is wrong! Can you check my latest post please?

    BJT Biasing - Simple easy 1 minute answer!

    Omg. I feel so dumb! Vb = 2V Ib = 1.625 x 10^-5 Amps = 16.25 uA! Ic = 8.125 x 10-4 Amps = 0.8125 mA! So, Ie = 16.25uA + 0.8125mA = 0.82875mA! And then calculating Vce: 10v = (rc)(ic) + vce + (re)(ie) 10v = (2000)(8.125 x 10^4) + vce + 0 so, vce = 8.375 And then vcb: vce = vbe + vcb...

    BJT Biasing - Simple easy 1 minute answer!

    I did this... From calculating the base voltage i get: Vb = 10V * (r1 / (r1 + r2) = 8 V. From the thevenins circuit - R1 || R2 = 80kΩ and then doing a kvl in this circuit i get: Vb = (80k)(Ib) + Vbe + (0k)(Ie) 8V = (80k)(Ib) + 0.7 + 0 7.3V = 80k*Ib So, Ib = 91.25uA! (which...

    BJT Biasing - Simple easy 1 minute answer!

    Yes - We do not have to construct this circuit or anything... He just wants us to understand some of the concepts... Is my Ib and Ic calculations correct? Based on that Ie = Ib + Ic would be correct? Thank you for your help so far! <3 (I am really really bad at circuits!) Lol!

    BJT Biasing - Simple easy 1 minute answer!

    I did that already...but I am not sure what to do with Re = 0 ohms. I calculated Ib to be 91.25uA And Vb to be 8V And Ic to be 4.56mA After the thevenins equalivant..I tried doing a KVL loop...and just get (Ie)*(Re) and Re = 0? Ahhh!

    BJT Biasing - Simple easy 1 minute answer!

    I think I am even more confused than I started? So if Ie is not 0 then I can proceed with using Ie = Ib + Ic? Do not really understand how that works?! :[

    Simple Diode Analysis Problem - Calculating Current/Voltage in a diode:

    So for this problem - Getting Id = 0.79mA and then solving for Vd I got 0.626V. , is this not the most precise result I can get for this problem? I'm not sure how to do the next iteration? To answer the problem, i got the following values: Total Current = 0.93mA Diode Current = 0.79mA...

    Simple Diode Analysis Problem - Calculating Current/Voltage in a diode:

    Oh! Sorry! Punched it in wrong! :] I = Idiode + Iload 0.93mA = Idiode + 0.14mA Idiode = 0.79mA And then plugging it in the ideal diode equation and solving for Vd I got 0.626 V?
