  • Evaluating the average probability of symbol error for different bandpass modulation schemes Comparing different modulation schemes based on their error performances. Channel coding: Transforming signals to improve communications performance by increasing the robustness against channel impairments (noise, interference, fading, ..) Waveform coding: Transforming waveforms to better waveforms Structured sequences: Transforming data sequences into better sequences, having structured redundancy. “Better” in the sense of making the decision process less subject to errors....

  • With Drupal, Web professionals can create full-featured Web sites with just a few clicks. Drupal’s core is compact and well documented, but much of Drupal’s immense power lies elsewhere—in external modules. Drupal’s Building Blocks is an authoritative tutorial, reference, and cookbook for Drupal’s most valuable modules.

  • Originally the term ‘protein module’ was coined to distinguish mobile domains that frequently occur as building blocks of diverse multidomain proteins from ‘static’ domains that usually exist only as stand-alone units of single-domain proteins. Despite the widespread use of the term ‘mobile domain’, the distinction between static and mobile domains is rather vague as it is not easy to quantify the mobility of domains.

  • Laboratory Procedure I . PCM Familiarization A. The analog to digital conversion properties of the PCM was investigated in the last experiment. The “start” bit and the 7 data bits and two “stop” bits were identified. It was also found that if the parity switch is on, then the 1st stop bit is changed to an even parity bit. That is, the 7 data bits plus the parity bit will always be an even number (refer to figure 8 B) B. Set up Figure 8A. the MSB-LSB quantization switches are to be implemented using the Sample and hold and Quantizer blocks....

  • This module explains how to use some common statements in C#. It also explains how to implement exception handling in C#. In particular, it shows how to throw errors as well as catch them, and how to use try-finally blocks to ensure that an exception does not cause the program to stop before cleaning up. After completing this module, students will be able to: Describe the different types of control statements. Use jump statements. Use selection statements. Use iteration statements. Handle and raise exceptions in a C# application....

  • (BQ) This manual covers both PSIM* and its add-on Motor Drive Module and Digital Control Module. Functions and features for these two modules are marked wherever they occur. The Motor Drive Module has built-in machine models and mechanical load models for drive system studies. The Digital Control Module, on the other hand, provides discrete elements such as zero-order hold, z-domain ransfer function blocks, quantization blocks, for digital control analysis.

  • Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

  • The 20-pair TrueNet® CopperTen® termination block is designed to suit five incoming and five outgoing four-pair Category 6a cables. Each IDC slot is color-coded to allow for accurate termination of each of the four pairs. The CopperTen termination block utilizes a disconnect feature making it ideal for Patch-by-Exception installations and can also be patched as a traditional cross-connect. The cable manager at the rear of the module ensures that cables are held in place securely without the need for Velcro ties....
