Margaret Alston,Kerri Whittenburyhe output signal .(j.) is simply obtained by multiplication of the spectrum of the input signal .(j.) by the transfer function .(j.) (1.10). In this chapter we derive the corresponding relations for discrete-time systems, which look quite similar.臭了生气 发表于 2025-3-23 21:59:10

According to the chosen approximation method, a number of more or less complex algorithms are available, iterative or analytic, that in most cases require computer support.调情 发表于 2025-3-23 22:39:13

Margaret Alston,Kerri Whittenbury) is calculated by convolution of the input signal .(.) with the impulse response .(.) of the system (1.1). In the frequency domain, the spectrum of the output signal .(j.) is simply obtained by multiplication of the spectrum of the input signal .(j.) by the transfer function .(j.) (1.10).
