Table 1.Truth Table for the 74LS138, a 3-to-8 Line Decoder If a multiplexer or encoder hasN outputlines, then it has2Ninputlines. A common example of a decoder/demultiplexer IC is the 74LS148, which is a Low-Power Schottky TTL device that has 8 input lines and 3 output lines. The 7...
a chromatography method prediction tool, and an alternative metabolomics algorithm for robust processing of multidimensional data acquired in state-of-the-art LC-IM-MS instrumentation. The advantages of using LC-IM-MS with DIA and PeakDecoder enable high-throughput analyses with increased ...
Strobe S acts as an enable signal. If strobe =1, 74151 is disabled and output y = 0. If strobe = 0, 74151 is enabled and functions as a multiplexer. Table 3.1 shows the multiplex function of 74151 in terms of select lines. Table 3.1 16 ...
Table 5 Detailed comparison of the proposed method with the existing models using three different datasets. Full size table Qualitative results Figure 4 Qualitative results of our proposed method on a test sample from the JSRT dataset. From top to bottom: inputs, groundtruth labels, and the segm...
When this decoder is enabled with the help of enable input E, then its one of the four outputs will be active for each combination of inputs. The operation of this 2-line to 4-line decoder can be analyzed with the help of its truth table which is given below....

Hence, it is mathematically justified to integrate the HAT model with an external LM using the density ratio method. In [181], an internal LM estimation (ILME)-based fusion was proposed to enable a more effective LM inte- gration. During inference, the internal LM score of an E2E model ...
