When considering data that has a time series, such as sound level or weather patterns, we can represent it usingits value at successive time points (val(t=0), val(t=1), ...). This is called a time domain representation, and is bot the simplest representation and also the form that most daat is initially gathered. However, gthe time series can be represented in other ways, notabley frequency domain that treats the data as a sum of sine waves or similar functions.
