Solution:
$ \begin{aligned} \text { Given: }-+\mathrm{VSat} &=12 \mathrm{~V} \\\\ -\mathrm{VSat} &=-12 \mathrm{~V} \\\\ V_{H V}=7 \mathrm{~V} .\\ \end{aligned}\\ $
The hysteresis voltage $V_{1+v}$ is given by,
$ V_{H V}=\frac{2 R_2}{R_1+R_2} \cdot V_{\text {sat }}\\ $
$ \begin{aligned} &\therefore 7=\frac{2 R_2}{\left[R_1+R_2\right]} \times 12 \\\\ &\therefore \quad \frac{R_2}{R_1+R_2}=\frac{7}{24} \\\\ &\therefore \quad …
