Explanation Introduction: The ROM is the type of memory in which the data can only be read and not be written. The ROM comes under the category of the volatile memory as they store the data even when the system is turned on, thus the data can be retained later. The mask programmed ROM is non-volatile memory with the NMOS transistor either included or excluded selectively in the last stage of manufacturing so that the desired memory can be obtained. The table for the 4 bit output of different states of the sixteen states along with the product of the two bit variable is shown in table 1 Table 1 State 1 00 00 0000 2 00 01 0000 3 00 10 0000 4 00 11 0000 5 01 00 0000 6 01 01 0001 7 01 10 0010 8 01 11 0011 9 10 00 0000 10 10 01 0001 11 10 10 0010 12 10 11 0011 13 11 00 0000 14 11 01 0001 15 11 10 0010 16 11 11 0011 The 16 words into 16 rows and 4 NMOS transistors have control gate input in four columns so that required output is obtained

Quantization and Resolution

Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algori…
