First of all, frequency is the number wave cycles repeated per second, measured in Hz (hertz). So one cycle per second would equal 1Hz. So if you have a 100MHz cable this means that the cable can transfer 100,000,000 wave cycles of current in one second. One cycle of a wave could be from one peak in a wave to the next peak.
Next, bit rate and baud are factors of the speed of current or data transfer. Each 1 and 0 or on and off in a current represents one bit of data. Bit rate is the number of bits of data transfered in one second, measured in bps (bits per second). This means that if this byte of data 01010101 (8 bits) is transfered in one second then it would be measured as 8bps. Baud, or baud rate, is the number of times a current or data signal changes state or symbols per second. In relation, the bit rate is equal to the baud per second multiplied by the number of bits per baud (bps = baud per second * bits per baud). So, in this case, one symbol (01010101 or 11000111) containing 8 bits and changing 1000 bauds per second would yield a rate of 1000 baud and 8000bps or 8Mbps (8 Megabits per second).
Now, having described the the differences in frequency, bit rate, and baud; these factors are all related to bandwidth. In fact, bandwidth is determined by all of these factors including one more factor, which is distance. Bandwidth the the maximum frequency at which data can be transfered effectively, which is measured in hertz. Bandwidth could also be said as the difference between the highest and lowest frequencies of a signal. This is the amount of space available to transfer data over a single wire or airwave. Bandwidth is determined by the frequency, speed, and distance of a signal. Frequency is the key factor though. High frequency means a slower speed or shorter distance, and low frequency means a faster speed or longer distance. If a signal has a high frequency, which would be wave cycles that are closer together, then either the speed has to decrease and the distance has to stay the same, or the distance has to decrease and the speed has to stay the same. If the frequency or the signal is low, which is wave cycles that are further apart, then the speed can increase and the distance stay the same, or the distance can increase and the speed stay the same. So, if you think about a cable with signal being sent across it as a highway and the data bits in the signal as the cars. If two car lengths is one wave length and both cars travel from point A to point B in one second, then the frequency would equal 1Hz because one wave cycle was completed in one second. Now, if we needed two bits of data (cars) to be transfered in one second from point A to point B across the cable (highway) then the bandwidth would be 1Hz. If we needed to get more cars across the highway in the same amount of time then the distance of the highway (cable) or the distance between the cars (data bits) would have to decrease and the speed of the cars could stay the same.
Hope this makes sense and is helpful for those of you with questions.

Frequency refers to the number of cycles per second in a signal, bit rate is the number of bits transmitted per second, and baud represents the signaling rate of a line. While frequency is a physical characteristic of a signal, bit rate and baud are more related to data transmission and the efficiency of the communication channel.

What two major theories that attempt to explain hearing are?
Two major theories that attempt to explain hearing are the place theory and the frequency theory. The place theory suggests that different sound frequencies activate different areas on the basilar membrane in the cochlea, while the frequency theory proposes that the rate at which nerve impulses are generated in response to sound waves determines pitch perception.
What is the relationship between breathing heart rate and exercise?
During exercise, the body requires more oxygen to fuel the muscles, which leads to an increase in breathing rate (respiratory rate) and heart rate to deliver more oxygenated blood to the muscles. This helps to meet the increased energy demands of the body during physical activity. Regular exercise can improve cardiovascular and respiratory system efficiency, resulting in lower resting heart rate and more controlled breathing.
How does a change in the required rate of return affect project's Internal Rate Of Return?
A change in the required rate of return will affect a project's Internal Rate of Return (IRR) by potentially shifting the project's feasibility. If the required rate of return increases, the project's IRR needs to be higher to be considered acceptable. Conversely, a decrease in the required rate of return could make the project's IRR more attractive.
What does a unit rate look like?
A unit rate is a ratio that compares two quantities, with one of the quantities equaling 1. For example, if you drive 60 miles in 2 hours, the unit rate would be 30 miles per hour, indicating the distance traveled per each hour.
Circuit diagram for heart beat counter?
A heart beat counter circuit typically consists of a heart rate sensor connected to a microcontroller (such as Arduino) which processes the sensor data and displays the heart rate on a digital display (such as an LCD screen). The heart rate sensor measures the electrical activity of the heart and converts it into a signal that the microcontroller can interpret. The microcontroller then calculates the heart rate based on the sensor data and displays it on the screen.
What is baud rate generator?
baud rate generator is a frequency divider
What is difference between baud rate and frequency?
baud rate is the rate of symbol changes...symbol can be of 1 bit, 2 bit , 3 bit etc.... Where as frequency is the inverse of rate of lowest unit in a digital transimission...
Is frequency of square wave is equal to baud rate?
When we consider the frequency of a square wave, we can indeed equate that with the baud (not baud rate), which is the number of pulses per second.
What is the difference between baud and baud rate?
Baud rate is the measure of how many times per second a signal makes a transition between two different states. The state of the signal can be a measurement of frequency, voltages, or phase angles to name a few. The Baud defines the number of signal events that occur in a transmitted signal.
Give an example of a signal for each what conditions the baud rate is equal to the bit rate the baud rate is greater than the bit rate and the baud rate is less than the bit rate?
Basically the baud rate can never be greater than the bit rate. Baud rate can only be equal or less than the bit rate. However, there are instances that baud rate maybe greater than the bit rate. In Return-to-zero or Manchester encoding, where there are two signaling elements, the baud rate is twice the bit rate and therefore requires more bandwidth.
How do you converion baud rate to symbol rate?
baud rate = symbol rate= modulation rate all the same thing
What is baud rate of the modem?
whats the baud rate of the modem of the computer
What is the Baud rate for 1024QAM?
It is impossible to answer that question. On the other hand if you assume this: - Baud rate = symbol rate - Bit rate = bits per second The following formula is valid: Baud rate = bit rate / 10 If 1024 QAM is used.
What is baud rate in 8051?
Baud rate is defined as the number of bits transmitted per sec.
Why clock frequency of 6.14 mhz is used in 8085 microprocessor?
Because it is the top operating speed for that IC
What does baud rate measure?
The baud rate measures the number of times the transmission medium can change its state in one second, which is the number of discrete signals in a given second. Baud rate is the speed of transmission when using modems over telephone lines.
What is bit rate of Ethernet when Manchester encoding is used?
bit rate is half the baud rate
