Abstract
This article deals with the study of Toeplitz operators associated with the deformed windowed Fourier transform. The primary aim is to study the Toeplitz operators, particular their trace class properties and demonstrate that they belong to the Schatten-von Neumann class of operators. Nevertheless, significant attention is also devoted to a spectral analysis by examining the eigenvalues and eigenfunctions of the time-frequency Toeplitz operator. Towards the culmination, the spectrograms associated with the deformed windowed Fourier transform are also studied in detail.
