What is need of voltage follower circuit?
It's a buffer circuit - it provides a high impedance input, and low impedance output with ~ unity gain. If you have a circuit that cannot drive much power, you can use a voltage follower to help. Also, if the input or output of a circuit needs to stay a specific value, such as with filters, you can easily control this due to the isolation the voltage follower provides.
How does an active voltage divider network for Photomultiplier work?
Conceptually, it's the same as a passive voltage divider but with buffer amplifiers on the outputs connected to each dynode - the primary purpose of this is that it decreases the source impedance so that current flowing into the dynodes does not affect the voltages applied to any significant extent.
What is difference between single double and circular buffer?
single buffer : you read and write on the same buffer, can be messy if both reading and writing take place at the same time.double buffer : you read one buffer and you write the other one. When both reading and writing are complete, the buffers are swapped. It solves the problem of simultaneous reading and writing but requires synchronization.circular buffer : this a buffer with two pointer : read and write. If both pointers are equal, the buffer is empty.For each write operation, the write pointer advances and each time data is read back, the read pointer advances. It is circular because when a pointer reaches the end, it wraps back to the beginning.It may be used to implement a queue which allows simultaneous reading and writing without synchronization as long as the buffer is not full.A double buffer is basically a circular buffer of size 2 and a single buffer is basically a circular buffer of size 1.
What do you mean by buffer in micro processor?
A buffer is merely a temporary storage used in conjunction with computation.
Why gets function gives a warning every time you compile a c program?
It is unsafe. In order to use gets() safely, you need to know how many characters you will be reading to ensure your character buffer is large enough: char buffer[10]; while (gets (buffer) != 0) { ...process buffer... } The above code has undefined behaviour when the number of characters read is 10 or more (you need one character for the null-terminator). This is because the character buffer, str, decays to a pointer (referencing &str[0]) and the function, gets(), cannot determine the number of characters in a buffer by its pointer alone. The gets() function was dropped from the C standard in 2011, however some implementations still include it. To avoid the warning, use the fgets() function instead. This allows you to specify the length of your buffer and (when used correctly) prevents buffer overflow. char buffer[10]; while (fgets (buffer, 10, stdin) != 0) { ...process buffer... }
What do you mean by voltage buffer?
A voltage buffer is a circuit that will buffer a source from an output.
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
What is voltage follower?
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain
Application of a common - collector amplifier circuit?
Common collector amplifier can be used as a voltage buffer and in impedance matching
What is the effect of buffer on RBC?
A buffer amplifier takes an input voltage, perhaps from a circuit that is unable to put out a large current, it then drives it's own output from a separate power supply, thus isolating the original signal from the load you are applying it to.
What is pinned buffer in oracle?
The buffer is in used is called as pinned buffer
A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
Is a chemical or combination of chemicals that keeps pH within normal range?
A buffer. just got the answer correct on a bio exam
Is HCl a pH buffer?
No, it is not a buffer.
What is buffer P2?

What is pseudo buffer?
a solution which does not fulfills the property of a buffer solution but act as buffer solution.
How are the buffer and buffer spring retained inside the extension tube?
using a buffer retainer
