Duration: 8 min 17 s
Description: In this lecture, we introduce some basic concepts and definitions that we will use throughout our course on Thermodynamics. In particular, we introduce definitions of a system, surroundings, system boundary, working substance, components, phases, properties of substance (intensive and extensive properties).

In this lecture, we will introduce the Fourier Transform for spectral analysis of non-periodic signals. We look at the derivation of the Fourier Transform of a non-periodic function, starting from the Fourier Series of a periodic function. In the limit of time period tending to infinity, the periodic function tends to a non-periodic function and the Fourier Series gives way to Fourier Transform. (c) Supreet Singh Bahga
