RXJS How to convert Observable<T[]> to Observable<T>

I would like to take an Observable<T[]> and convert it to an Observable<T> such that each array from the Observable<T[]> is broken up and the individual elements of the arrays are then emitted, separately, via the Observable<T>.

Is there a standard operator for doing this? I've searched around but haven't found anything. Thanks.

After being pointed in the direction of concatMap/flatMap, I came up with the following general solution:

var source: Observable<T[]>;
...
var splitSource = source.flatMap<T>((x:T[]) => { return Rx.Observable.fromArray(x); });
