Absolute value of magnitude?View attachment 97656
Must be briefed constant value even start drawing , use this equation ===> 20 Log(-10)
They are supposed to put frequency on the x-axis, and the absolute value of H(s) on the y-axis. Absolute value is Always positive. The correct formula is:Going on a limb here, but it strikes me as an imaginary number, similar to the square root of -1.
Your question lacks context. As a pure math question there are a couple of answers:what is 20 log (-10) =?
Express -10 in the exponential form.what is 20 log (-10) =?
Sure. In fact, there are infinitely many values of x for which 10^x yields -10. Here's one of them:Can you figure out a case where 10^x=-10?
