Abstract
Methods, apparatus, systems, and articles of manufacture are disclosed to enable Digital Satellite Equipment Control (DiSEqC) communication between an antenna and a processor. An example apparatus includes a receiver to be coupled to an antenna by a cable and configured to bidirectionally communicate with the antenna via a communication signal having a periodic waveform, wherein the receiver further includes a low dropout regulator (LDO) pass transistor to be coupled to the cable and configured to generate a current signal based on the periodic waveform of the communication signal, a current envelope detector circuit coupled to the LDO pass transistor configured to generate a voltage signal based on the current signal, and a processor. The processor is coupled to the current envelope detector circuit and configured to process the voltage signal generated by the current envelope detector.
