The circuit in Figure 1 complements a previous Design Idea (“SSB modulator covers HF band,” EDN, Sept 30, 1999, pg 122). The modulator employs a phasing network to split a low-frequency audio signal ...

The generation of single sideband (SSB) signals first came to my attention via ham radio back in the early 1960s. My call was then and still is WA2IBH. The best phonetic I had for that call sign was ...

As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many occasions, such as electronic warfares, wireless communications and modern radar systems. Initially, ASK ...

In the recent decade, various schemes of field recovery with direct detection have been investigated in short-reach optical communications. Since direct detection generally provides only intensity ...

This year, we recognize John R. Carson for two major contributions to communications technology: the invention of single-sideband (SSB) modulation and his rule for estimating frequency modulation (FM) ...

LASER COMPONENTS supplies the ModBox-CBand-CS-SSB which is an Optical Transmitter Frequency shifter based on high order optical Carrier Suppressed Single Side Band modulation. The ModBox operates in ...

LASER COMPONENTS supplies iXblue‘s modulator bias controllers and board types, showing a very low noise sensitivity yielding a significant reduction of the required ...

Single Sideband, or SSB, has been the predominant amateur radio voice mode for many decades now. It has bee traditionally generated by analogue means, generating a double sideband and filtering away ...

Regarding Frank Foti’s SSB FM proposal as described in “A Method to Improve Conventional FM Stereo” (Radio World Engineering Extra, Oct. 13): The main computational load required to implement this ...
