BAB 1

1-1 suhu, kecepatan, tekanan dan posisi.

1-11 karena bilangan biner hanya terdiri dari angka 0 dan 1, sehingga mudah direpresentasikan dalam sistem digital dengan dua tegangan yang berbeda seperti +5 V=0 dan 0 V= 0.

b) F416 =Solusi:4 x 160 = 415 x 161 = 240F416 = 4 + 240 = 24410

c) 9216 = Solusi:2 x 160 = 29 x 161 = 1449216 = 2 + 144 = 14610

d) AB16 = Solusi:11 x 160 = 1110 x 161 = 160AB16 = 11 + 160 = 17110

1-19 A computer programmer observes the following hex string when looking at a particular section of computer memory: 736B753433. (a) Assume that the memory contents are ASCII codes with leading zeros and translate this string into its alphanumeric equivalent.(b) The programmer realizes that the program recognizes only capital (uppercase)letters. Convert all letters in the alphanumeric equivalent to capital letters, and determine the new hex string.

2-5 Repeat Example 21 for a period of 200 ns.What is the frequency of a clock waveform whose period is 200 ns?Solusi:

2-15 To forward bias a diode, the anode is made more positive (positive/negative) than the cathode.

Problems2-4 (a) How long will it take to transmit the three ASCII-coded characters $14 in 8-bit parallel if the clock frequency is 8 MHz?(b) Repeat for $78.18 at 4.17 MHz.

2- 14If the load resistor (Rload) used in Problem 213 is changed to 470 ohm. describe what happens to Vout.

E2-1 Load the circuit file for Section 23. Read the instructions in the Description window.(a) Determine the three ASCII characters that are transmitted in serial.(b) Determine the number of serial bits transmitted.
