  • Can time domain data be complex?

    Analytic signals are complex-valued time-domain signals whose imaginary part is the Hilbert transform of their real part.

  • What is a complex signal?

    A complex signal consists of two real signals - one for the real and one for the imaginary part.
    The linear processing of a complex signal, such as filtration with a time-invariant linear filter, corresponds to applying the processing both to the real and the imaginary part of the signal.

  • What is the signal of time domain?

    In the time domain, the signal or function's value is known for all real numbers, for the case of continuous time, or at various separate instants in the case of discrete time.
    An oscilloscope is a tool commonly used to visualize real-world signals in the time domain.

  • What is the signal of time domain?

    Furthermore, the time domain can be used to analyze a wide range of signals, including audio signals, video signals, and even biological signals such as electroencephalograms (EEG).
    For example, in the case of an EEG, the time domain can be used to analyze the electrical activity of the brain over time.
