This paper describes a general method of applying error correction to synchronous digital d a t a systems. It includes, as a special case, the wellknown scheme of triplication with vote taking.

Traditional Time Division Multiple Access (TDMA) systems have shied away from using phase-locked-loops (PLL) primarily for the reason that they suffer from a phenomena called hangup, where during t

The demand for new services offered by the Bell System is increasing rapidly. Many of the services have performance requirements that are more critical than those of voice message telephone.

N January 25, 1915, telephone service was, with due ceremony, inaugurated between the Atlantic and Pacific Coasts of this country.

HE growth of the field of electric wave filters since their original discovery by Dr. G. A. Campbell shows the filtering action by no means inheres in any particular physical configuration.

HE well known expansion theorem given by Heaviside in Vol.

A graph is called a multistage graph if its vertex set can be partitioned into subsets Vs, for some number s, and its edge set into subsets Ei,..., Es-1 such that Ei connects V,- with V,+i.

HE Reciprocal Theorem, an interesting a n d extremely imp o r t a n t relation of wide applicability, which was discovered by Lord Rayleigh, is stated by him in the language of electric circuit the

Distributed applications use Bloom filters to transmit large sets in a compact form. However, attackers can easily disrupt these applications by using or advertising saturated filters.

Conventional radio-frequency (RF) power amplifiers operating with wideband signals, such as wideband code-division multiple access (WCDMA) in the Universal Mobile Telecommunications System (UNITS)
