In this paper, we discuss the linearity of a sequence space $\Lambda_{p}(f)$, and the conditions such that $\ell_{1} = \Lambda_{1}(f)$ holds are characterized in term of the essential bounded variation of $f\in L_{1}(\mathbf{R})$, i.e. $\ell_{1} = \Lambda_{1}(f)$ if and only if $f\in BV(\mathbf{R})$.
