Blocking in multiwavelength TDM networks
Telecommunication Systems, 1999This paper examines the relative importance of wavelength conversion and time?slot interchange in improving the performance of multiwavelength time?division multiplexed networks. It is shown that, in networks with a small number of wavelengths, each carrying a large number of time?division multiplexed channels, significant performance improvements are ...

TDM OF THEOPHYLLINE—COMPLIANCE EVALUATION
Journal of Clinical Pharmacy and Therapeutics, 1988Non-compliance to dosage regimes is an important clinical problem with severe repercussions for the management of chronic illnesses requiring continued treatment. In the present study, we evaluated the degree of non-compliance in a group of 100 patients with chronic asthma undergoing continued treatment with theophylline, and the effect of the ...

Development of a TDM/FDM Transmultiplexer
IEEE Transactions on Communications, 1978Recently, digital systems such as digital telephone switching systems and digital transmission paths are being introduced more and more into communications networks in which signals are handled with Time Division Multiplex (TDM). There still exists, on the other hand, a number of analog transmission paths in which signals are multiplexed with Frequency

The Spectrum of a TDM PPM Signal
IEEE Transactions on Communications, 1974The spectrum of a time-division-multiplexed (TDM) pulse-position-modulated (PPM) signal consists of three parts-the continuous part, which is simply the sum of the continuous parts of the spectra of the separate channels; lines on harmonics of the maximum overall pulse-repetition frequency (PRF), which are also independent of any permutation among the ...

A TDM-based multibus packet switch
IEEE Transactions on Communications, 1992A novel packet switch architecture using two sets of time division multiplexed (TDM) buses is proposed. The horizontal buses collect packets from the input ports while the vertical buses distribute the packets to the output ports. The two sets of buses are connected by a set of switching elements which coordinate the connections between the horizontal ...
