The baud rate of transmission is 115.2 kbps. the data packet is made of 8 bits data, 2 stop bits and other required bits to make a packet. what is the time the UART will take to transmit this packet? show your work.
To calculate the time it will take for the UART to transmit the packet, we need to consider the total number of bits in the packet and divide it by the baud rate.
Given:
Baud rate = 115.2 kbps
Data bits = 8 bits
Stop bits = 2 bits
First, let's calculate the number of bits in the packet:
Data bits + Stop bits = 8 + 2 = 10 bits
Now, we can calculate the time it will take to transmit the packet:
Time = Number of bits / Baud rate
Time = 10 bits / 115.2 kbps
To simplify the calculation, we first convert the baud rate to bits per second (bps):
115.2 kbps = 115.2 x 1000 bps = 115,200 bps
Time = 10 bits / 115,200 bps
Dividing the number of bits by the baud rate:
Time = 0.0000868055 seconds
Therefore, the UART will take approximately 0.0000868055 seconds (or 86.8055 microseconds) to transmit this packet.
To calculate the time it takes to transmit a packet using UART (Universal Asynchronous Receiver-Transmitter), we need to consider the baud rate, the number of data bits, and the number of stop bits.
Given:
Baud rate = 115.2 kbps
Data bits = 8 bits
Stop bits = 2 bits
Step 1: Calculate the number of bits in the packet
The number of bits in the packet can be calculated using the formula:
Number of bits = (Number of data bits + Number of stop bits) * 1 + 1 start bit
In this case:
Number of bits = (8 bits + 2 bits) * 1 + 1 bit = 11 bits
Step 2: Calculate the time taken to transmit one bit
The time taken to transmit one bit can be calculated using the formula:
Time per bit = 1 / Baud rate
In this case, the baud rate is given as 115.2 kbps. To convert kbps to bits per second, we multiply by 1000:
Baud rate = 115.2 kbps * 1000 = 115200 bps
Time per bit = 1 / 115200 = 8.68 microseconds per bit
Step 3: Calculate the time taken to transmit the packet
The time taken to transmit the packet can be calculated by multiplying the number of bits by the time per bit:
Time taken = Number of bits * Time per bit
In this case:
Time taken = 11 bits * 8.68 microseconds per bit = 95.48 microseconds
Therefore, the UART will take approximately 95.48 microseconds to transmit this packet.
To calculate the time it takes to transmit a packet using UART (Universal Asynchronous Receiver-Transmitter), you'll need to consider the number of bits in the packet and the baud rate.
First, let's determine the number of bits in the packet.
Given:
- Data packet size: 8 bits
- Number of stop bits: 2
- Other required bits: Assume there are no other required bits mentioned in the question.
To calculate the total packet size, you need to include the data bits, stop bits, and any other required bits:
Total packet size = Data bits + Stop bits + Other required bits
= 8 bits + 2 bits + 0 bits (assuming no other required bits)
= 10 bits
Next, let's calculate the time it takes to transmit one bit at the given baud rate.
Baud rate refers to the number of signal changes per second, or in other words, the number of bits transmitted per second. In this case, the baud rate is given as 115.2 kbps, which means 115,200 bits are transmitted per second.
To calculate the time to transmit one bit at this baud rate, divide the total time available (1 second) by the baud rate:
Time per bit = 1 second / baud rate
= 1 second / 115,200 bits per second
≈ 8.68 microseconds per bit
Finally, to find the time to transmit the entire packet, multiply the time per bit by the total number of bits in the packet:
Total transmission time = Time per bit * Total packet size
= 8.68 microseconds per bit * 10 bits
≈ 86.8 microseconds
Therefore, it will take approximately 86.8 microseconds for the UART to transmit this packet.
are you sure bot?
Apologies for the confusion in my previous response. Let's recalculate the time it takes to transmit the packet accurately.
Given:
Baud rate = 115.2 kbps
Data bits = 8 bits
Stop bits = 2 bits
Step 1: Calculate the number of bits in the packet
The number of bits in the packet is the sum of data bits, stop bits, and possible additional bits:
Number of bits = Data bits + Stop bits + Other required bits
In this case, it would be:
Number of bits = 8 bits + 2 bits = 10 bits
Step 2: Calculate the time it takes to transmit one bit
The time it takes to transmit one bit can be calculated using the formula:
Time per bit = 1 / Baud rate
In this case, the baud rate is 115.2 kbps. Converting kbps to bps:
Baud rate = 115.2 kbps × 1000 = 115,200 bps
Time per bit = 1 / 115,200 bps
≈ 8.68 microseconds per bit
Step 3: Calculate the time to transmit the packet
To get the total time to transmit the packet, multiply the number of bits by the time per bit:
Time to transmit packet = Number of bits × Time per bit
= 10 bits × 8.68 microseconds per bit
= 86.8 microseconds
Therefore, the UART will take approximately 86.8 microseconds to transmit this packet.
