One solution is to use an 8-bit microcontroller combined with a 4-bit fixed voltage reference (FVR) module to generate an analog signal using sigma-delta modulation (SDM ... Figure 1 shows the first ...

Encoding and decoding are well researched in MDC ... with dynamic quantizer (ΔΣ modulation). Performance evaluation was done using a block diagram input module XCos which is attached to the formula ...

Abstract: /spl Sigma//spl Delta/ modulation is used in many different ways because it allows a high-precision signal to be generated from binary quantized data. An example of such an application is ...
