The Dolby Noise-Reduction System

The Dolby Noise-Reduction System, May 1969 Electronics World - RF CafeDolby noise reduction is not really directly applicable to the RF Cafe theme, but I included this article for two reasons. First, a lot of people are familiar with the Dolby system and do not know its history or technical details. Second, the general subject of noise reduction and dynamic range, avoidance, mitigation, etc., is of interest even if the methods of dealing with audio noise is different from radio signal noise. Dolby's companding (compressing-expanding) circuitry was an adaptation of analog video noise reduction used in television. Interestingly, a lot of people evidently were skeptical about ...

Mac's Service Shop: Salvaging Dunked Radios

Mac's Service Shop: Salvaging Dunked Radios, July 1972 Popular Electronics - RF CafeThis 1970s-era Mac's Service Shop story made me think about all the cellphones today being dunked in toilets, swimming pools, lakes, and washing machines. Of course back in Mac's day not everyone was walking around with an electronic device tucked into his or her pocket waiting for its absentminded owner to bend over or drop his/her drawers. At the time, far more wallets made the dive than transistor radios. I won't bother linking to any articles about how to best dry your dunked phone because there are hundreds - nay, thousands - of them out there.

Light Modulation of Semiconductors

Letters from Our Readers, May 1969 Electronics World - RF CafeThis letter to the editor column from a 1969 issue of Electronics World got my attention because of the submission by reader Walter T. Stevenson. He mentions having discovered that semiconductors, in his case a transistor, could have their junction conductance modulated by ambient light sources, in his case a fluorescent light. Evidently some of the early transistors were shipped on a substrate where the die was potted with a translucent epoxy compound that permitted some light penetration. At least one manufacturer switched to an opaque compound as a result of Mr. Stevenson's report. I remember the first I experienced the phenomenon was as a technician working ...

LC Filters

LC Filters, April 1969 Electronics World - RF CafeInductor-capacitor (LC) series and parallel combinations comprised the first lumped element electrical filters for frequency discrimination. Below a few MHz, with a little judicial placement of components and treatment of lead lengths, building a successful LC filter is not hard, and the measured response physical result looks very much like the predicted response - provided the circuit model is sufficiently accurate. Above 50 MHz or so, very careful attention must be paid to parasitic elements (inter-turn capacitance, lead inductance, cross-coupling) to get a good response. The advent of surface mount components has made higher frequency LC filter ...

Direct-Impedance Amplification

Direct-Impedance Amplification, April 1936 Radio-Craft - RF CafeI tried to find some information on "direct-impedance amplification," but alas none could be located. At first, I suspected that it being in the April edition of Radio-Craft might have meant it was a ruse on readers, especially since author L. Mitchell Barcus focused on the nearly sub-audible portion of the sound spectrum down to around 16 Hz. Careful reading of the article reveals, however, that his pièce de résistance was designing the circuit with a minimum of biasing resistors, capacitors, and inductors that might otherwise attenuate low frequencies. Success was in the form of direct coupling of stages sans Rs, Ls, and Cs. I'm guessing the ...
