Resolution Definition and 313 Threads

Dispute resolution or dispute settlement is the process of resolving disputes between parties. The term dispute resolution is sometimes used interchangeably with conflict resolution, although conflicts are generally more deep-rooted and lengthy than disputes. Dispute resolution techniques assist the resolution of antagonisms between parties that can include citizens, corporations, and governments.

    Why is oversampling by 4^n times necessary for increasing ADC resolution?
