Energy ,dominant frequency, power , bandwidth of a discrete time signal

I have finally arrived in obtaining an array of 2000 samples which corresponds to amplitude of a given signal. eg:[ 0 .001 .003 .0035 .0037.............................] total 2000 samples

How can i find the energy, power, dominant frequency and bandwidth of this discrete signal

I am not sure, but there must be some formulation to calculate energy, power, dominant frequency and bandwidth using amplitude.
