Just a little mod…

Just about to plunge into the marking season here, and this can be good and bad… if the marking goes well I usually reward myself by doing a bit of programming between every ten scripts or so. On the other hand, if I don’t get myself into the zone, and the marking is going really slowly, I’ll probably not get the time to do another demo in the next month. Not really a big issue… I don’t actually have one in mind to do at the moment.

I did attend a lecture by a colleague recently in which he was demonstrating crosstalk… and that struck me as a fairly quick demo to get up and running. Might be based on the existing transmission line demo, which itself might get a bit of polishing up… it’s not exactly a model of user-friendliness at the moment.

All I have to show for this week is a slight mod to the analogue ac simulator. The frequency response curve used to be rather unintelligent; it just sampled the outputs over a set series of frequencies equally spaced between the smallest and largest frequencies currently displayed. This resulted in some rather unhelpful and inaccurate graphs when there were some high Q-factors being used. The new version concentrates the readings where the output is changing the most rapidly, which helps give much more accurate-looking readings in these cases. So I’ll be able to stop apologising about these misleading graphs when I use this myself.

Right – that’s all for a little while now. Tomorrow a huge pile of scripts hits my desk, and life will get a bit strange for a while…
