Assume the transistors in Figure P14.33 have $\beta_{\mathrm{F}}=100 . V_{B E}=0.6 \mathrm{~V}$, and $V_{C E(S A T)}=0.1 \mathrm{~V}$; the diode has $V_F=0.6 \mathrm{~V}$. (a) Calculate $V_{I L}, V_{O L}$, and $V_{O H}$. (b) What is the forced beta, $\beta^*$, for $Q_2$ when the output is low? (c) Construct a truth table for this circuit.
