    Filter shape from poles and zeros

    Im not sure if bode diagrams are relevant, this topic I'm doing is on digital signal processing. Really i just need some conditions on the poles and zeros for different types of filters

    Filter shape from poles and zeros

    So basically on a real and imaginary axis you would plot the poles and zeros that are found from the numerator and the denominator. Poles are represented as X and zeros are represented as o. Just by looking at a graph i want to be able to observe what type of filter it is, which is what I am...

    Filter shape from poles and zeros

    Hey guys, I am learning about the filter shapes deduced from the poles and zero plots, however a lot of sources are describing it differently with no logical explanation. I want to know what exactly the poles and zeros do between the range Ω = 0 and Ω = π. One source i read explains if the pole...

    Graduate Wide bandgap semiconductor -- why higher temperature tolerance?

    well silicon are currently used in most integrated devices due to its high thermal properties. i was wondering if the thermal coefficient of semiconductors were higher than that of silicon would that mean it would be able to achieve higher frequencies due to its wider bandgap?

    Graduate Wide bandgap semiconductor -- why higher temperature tolerance?

    I was wondering if anyone knows the relationship with temperature and frequency tuning in wide bandgap semiconductors. I just want to know why wider bandgaps have higher temperature tolerance and why does that mean high frequencies can be achieved? Explanation with formulas would be great!
