This is what I understand:

1. It is a common base circuit

2. There is a resonant circuit with a small signal source at the emitter.

3. qualitatively I know that at resonance, the impedance will be the lowest, therefore Vout (collector voltage) will be the lowest at this resonant frequency. (lower impedecence->more current through collector/emitter->more voltage drop across Rc.

I just do not understand how to go about starting this analysis. Can you guys help? How can I numerically calculate the resonant frequency?

Here is the circuit:
