Consider the Schottky TTL circuit in Figure 17.33. The transistor parameters are \(\beta_{F}=30\) and \(\beta_{R}=0.1\) (for each emitter).

(a) Determine all base currents, collector currents, and node voltages for \(v_{X}=v_{Y}=0.4 \mathrm{~V}\).

(b) Repeat part (a) for \(v_{X}=v_{Y}=3.6 \mathrm{~V}\).
