Can someone explain to me why sometimes I see the DTFT as functions of capital omegas or e^(jomega).
I'm failing to see the reason.

Variable notation for DTFT stands for variable notation for Discrete Time Fourier Transform. It is a mathematical representation used to analyze and process discrete-time signals in the frequency domain.
DTFT differs from other Fourier transforms in that it operates on discrete signals, while other transforms are used for continuous signals. DTFT is also defined over a finite range of frequencies, while other transforms are defined over an infinite range.
The commonly used variables in DTFT are n for the discrete time index, x[n] for the discrete-time signal, and X(ejω) for the DTFT of x[n] at frequency ω.
Variable notation is used in practical applications of DTFT to represent the input signal and its corresponding frequency domain representation. It allows for easier manipulation and analysis of the signal in the frequency domain, which can provide useful insights into the characteristics of the signal.
One limitation of using variable notation for DTFT is that it is only applicable to discrete-time signals and cannot be used for continuous-time signals. Additionally, the notation can become more complex when dealing with multi-dimensional signals or signals with infinite duration.
