A more detailed proof based on Matt's answer. Let $n_0$ be the argument to $\max\{|y[n]|\}$, i.e. $\max\{|y[n]|\} = |y[n_0]|$. We can always find $x[n]$ as a series of +1's and -1's, s.t. $$|y[n_0]| = ... • 43 2 votes Accepted ### Constructing an input signal whose response is determined by the impulse response You're right that you generally can't find a sequence x[n] such that$$y[n]=\sum_{k=-\infty}^{\infty}\big|h[k]\big|\tag{1}$$is satisfied for all values of n, but that's also not necessary. It is ... • 80.2k 2 votes Accepted ### Analog LTI system impulse response @Gunners Assuming that the t variable is continuous then your system is continuous (analog). In which case there is no H(z). As for the question: "What would you do to identify the impulse ... • 4,868 1 vote Accepted ### Convolution: graphing output y(t) with given input x(t) and impulse response h(t) @Gunners You can work your problem in two parts. The first part is: the output with just the single +2 impulse input that occurs at time = 0 seconds. The second part is: the output with just the ... • 4,868 2 votes ### Impulse response out of a modal model, how is it gotten? That's the impulse response of a generic damped resonant filter. Derivations abound. If you understand continuous-time frequency-domain analysis, consider a filter with transfer function$$H(s) = \...
