문제

1. Program in C language to print as follows: --- Type the values of 5 sampled points: 0 1.2 1.5 2.3 2.5 Digitized signal after quantization and coding is 100 100 101 101 110 --- 2. Cosider followings - The analog input voltage level is from - 5V to 5V - The quantization level is 8. - -5V is mapped to Quantization level 0 and 0V is mapped to Quantization level 4.
