Memories are bigger, faster - and cheaper: Semiconductor use is growing; cores are improving; bubbles, optics, and charge transport are on the wayG.C. Feth1973IEEE Spectrum
Optical transmission utilizing injection light sources: Injection light sources give optical transmission systems such versatility that the promised potential of these systems might be realized sooner than anyone expectedK. KonnerthB.R. Shah1970IEEE Spectrum
Delta modulation: Better communications are possible when the signals produced by the human voice are changed into a series of binary digits. One conversion method offers special advantagesH.R. Schindler1970IEEE Spectrum
Data transmission: a direction for future development: Because the public telephone network was designed only for voice communication, problems arise when data communication is attempted on this same network. Data waveforms can be converted for ease of handling but it is difficult to match the discontinuous flow of data from a terminal to the continuous flow of information in the communication channelHarry Rudin1970IEEE Spectrum
