Draw XOR using NAND gate?
Given two inputs, A and B. Use one NAND as an inverter (one source to both inputs) for A. Do the same for B. Use one NAND gate with inputs \A (not A, the output from the first gate) and B. Use one NAND gate with inputs A and \B. Use one last NAND gate with inputs coming from the two previous gates. Its output will behave like an XOR gate. Alternatively: Gates G1, G2, G3, G4, arrange in a diamond with G1 and G4 at the left and right vertices, A input along top edge, B input along bottom edge. G2 at top center, G3 at bottom center. A goes to G1 and G2, B goes to G1 and G3, G2 and G3 go to G4. Net list: A - G1i1 A - G2I1 B - G1i2 B - G3I2 G1o - G2i2 G1o - G3i1 G2o - G4i1 G3o - G4i2 G4o - A^B
The vector representation of a convolutional code is g1=[1 1]and g2=[1 0]. If the received sequence is 11 11 01 10, please use Viterbi Algorithm to decode it. Please show the full trellis diagram, including the updated trellis state metrics?
The vector representation of a convolutional code is g1=[1 1] and g2=[1 0]. If the received sequence is 11 11 01 10, we can use Viterbi Algorithm to decode it. The full trellis diagram, including the updated trellis state metrics, is shown below: Time t1: State 0 (00): Metric = 0 State 1 (10): Metric = 0 Time t2: State 0 (00): Metric = 0 + (1-1)^2 + (1-1)^2 = 0 State 1 (10): Metric = 0 + (1-1)^2 + (1-0)^2 = 1 Time t3: State 0 (00): Metric = 0 + (1-1)^2 + (1-1)^2 = 0 State 1 (10): Metric = 1 + (1-1)^2 + (1-0)^2 = 2 State 0 (01): Metric = 0 + (1-1)^2 + (0-1)^2 = 1 State 1 (11): Metric = 0 + (1-1)^2 + (0-0)^2 = 0 Time t4: State 0 (00): Metric = 0 + (1-1)^2 + (1-1)^2 = 0 State 1 (10): Metric = 2 + (1-1)^2 + (1-0)^2 = 3 State 0 (01): Metric = 1 + (1-1)^2 + (0-1)^2 = 2 State 1 (11): Metric = 0 + (1-1)^2 + (0-0)^2 = 0 Therefore, the decoded sequence is 11 11 01 10.
Together the G1 phase S phase and G2 phase are called?
interphase
What is a part of inter-phase?
g2 phase
Is G1 phase part of the interphase?
G1 is part of the interphase. The cell cycle is: mitosis, G1, S (synthesis), G2 and finally mitosis again. G1, S and G2 are all part of the interphase.
What are parts of interphase?
The three main parts of interphase are G1 phase, S phase, and G2 phase. During G1 phase, the cell grows and performs its normal functions. In S phase, the cell replicates its DNA. Finally, in G2 phase, the cell prepares for cell division.
Together, the G1 phase, S phase, and G2 phase are called?
Interphase and its is also the longest phase for the cell cycle.
Which is a part of interphase A.Prophase B.G1 phase C.Telophase D.Cytokinesis?
B. G1 phase. Interphase consists of three main stages: G1 phase, S phase (synthesis), and G2 phase. Prophase, telophase, and cytokinesis are stages of mitosis.
Which phase occurs directly after G1?
g3
What are the key differences between the G1 phase and G2 phase of the cell cycle?
The key differences between the G1 phase and G2 phase of the cell cycle are that the G1 phase is focused on cell growth and preparation for DNA replication, while the G2 phase is focused on further growth and preparation for cell division. In G1 phase, the cell is actively growing and carrying out its normal functions, while in G2 phase, the cell is preparing for mitosis by synthesizing proteins and organelles needed for cell division.
What does interphase consist of?
Interphase is the longest phase of the cell cycle and consists of three stages: G1 phase (cell growth), S phase (DNA replication), and G2 phase (preparation for cell division). During interphase, cells also carry out normal cellular functions and prepare for mitosis.
What are the key differences between the G1 and G2 phases of the cell cycle?
The key differences between the G1 and G2 phases of the cell cycle are that G1 is the first gap phase where the cell grows and prepares for DNA replication, while G2 is the second gap phase where the cell continues to grow and prepares for cell division. G1 phase is followed by the S phase where DNA replication occurs, while G2 phase is followed by the M phase where cell division takes place.
The time spent in G1 S and G2 periods of the cell cycle is called interphase?
Yes it is true that the time spent in G1 plus S plus G2 periods of cell cycle is called interphase. Once a cell crosses the halfway point of G1, it usually completes the rest of the cell cycle.
How does a nucleus in G2 differ from a nucleus in G1?
In G2, the nucleus has completed DNA replication so it contains twice the amount of DNA compared to G1. Additionally, the nucleus in G2 is preparing for cell division and checking for any DNA damage before entering mitosis.
