Homework Statement Hi, I am trying to solve the equation for I am and am having trouble Im=(Im+Ie+Ia)e^{-t/T} +Ia) Im-Ia = (Im+Ie+Ia)e^{-t/T}) ln^{Im-Ia}= Im+Ie+Ia this is were I get to but can't get the equation to work. Have I don't something incorrect in the second...

Thanks for the reply I have worked though it now and have solved it

v is across the diode from cathode to anode. Thanks for pointing that out

Hi all, I have been looking at this question and I am having trouble sketching the wave forms. I know that during the period 0<time<0.5 the MOSFET is OFF the diode is ON i = 4amps v =0 id=0 VDS=? Then during 0.5<time<1 period the MOSFET is ON the diode is OFF. i=0 v=...

Hi Berkeman, Thanks for the info, I missed that sign error in the first post. I have since re-worked the question and found that the Г to equal -4 1. Calculation the Reflection Coefficient at the load Г = (Rl-Zo)/(Rl+Zo) Г = (-30-50)/(-30+50) = -80/20 = -4 3. Would there be a...

Hi there, This is my first post so I hope that I am doing this correctly. I have put the question below and i am having troubles with numbers 3,5 and 6. Any help would be great. Cheers A transmitter with an output power of 200W operates at a frequency of 20MHz. It feed an antenna...
