It will be evident from the foregoing that a very large number of 

 circuit configurations of the feedback network will provide theoretical 

 stabilization of the oscillation frequency either with single stage or with 

 multiple amplifiers. Naturally, not all of these will be of the same 

 practical interest, since an undue complexity of the network may give 

 rise to difficulties in its adjustment and may increase the problem of 

 temperature compensation.
