    Ordinary and Partial Differential Equations (ODEs and PDEs) are usually subjects where Fourier analysis is introduced for a lot of undergraduates. Some study it from the first semester (electronic engineers) and for some its neither. Fourier touches a lot of subjects in physics and engineering, so don't worry, you'll get to it sooner or later.

    My personal experience involved a class titled "Lebesgue Measure and Fourier Analysis". It proved to be quite challenging for an undergrad course but also quite rewarding..Outside of strictly Math studies, well engineering has a variety of applications which involve Fourier transforms, such as signal processing..

    To be a bit more specific, it comes as a very natural tool in the analysis of Linear Time Invariant systems(LTI).

I took a class called "Systems and Transforms" where we introduced fourier transform and laplace transforms to solve differential equations of the form $y'' +ay' + y =f(t)$. In a class about PDE:s called "continuous systems" we introduced the fourier series and showed for which PDE:s the series was a solution. And now I'm taking a class in fourier analysis.

    Also modern number theory makes intense use of Fourier transform, Fourier series, and many other integral/spectral transforms and decompositions. Spherical harmonics, for example. When I teach (graduate) courses on number theory or modular forms or representation theory or... certainly Fourier series and Fourier transforms play a central role.
