Before commercial-scale quantum computing is a thing, however, researchers must clear some major hurdles. The technology has since been expected to be used to support communications, global positioning, and signal processing applications. But, if you sample a real signal $x_c(t)$, using the formula, $x_d[n] = x_c(nT)$ then the signal $x_d[n]$ is still real. then if you consider the ideal LPF in continuous domain $h_c(t) = \frac{\Omega_c}{\pi}\text{sinc}(\Omega_c t)$, which converts in the discrete coefficients of: $h_d[n] = \frac{\omega_c}{\pi}\text{sinc}(\omega_c n)$ , and both $h(t)$ and $h[n]$ are real also so where do complex numbers enter into the time domain anywhere? But even once quantum computing reigns supreme, its potential impact remains largely theoretical. First, we work with some matplotlib functions. But one thing is sure, is that it is all numeric data. Similary but not shown, we could have a real signal which would have a symmetric spectrum but we wish to introduce a assymmetry, and one example is predistortion, where instead of equalization compensating after a complex (assymetric) distortion has been introduced, we can distort the spectrum before it goes throught the distortion to pre-compensate-- this would be one example application of a real $x(t)$ with a complex $h(t)$. In the search for sustainable energy alternatives, hydrogen fuel, when produced without the use of fossil fuels, is serving to be a viable solution for reducing harmful greenhouse gas emissions.
