What is the use of buffer circuit?
One prominent application is this: Some circuits have an output impedance very high. If these circuits are coupled with another circuit of low input impedance, the desired functionality of the latter circuit will be drastically affected. Because the first circuit tries to deliver large voltage to the second and the second invariably requires small input voltage. To avoid the circuit disfunctionality, a buffer circuit (a circuit with high i/p impedance and a low o/p impedance) is used. Another application is in the delay matching. This is an advanced topic though. The technology is still new. In delay matching, the latter circuit requires a delay of say "n" seconds after the first circuit's output. A buffer circuit is used in such cases also. The circuit design is totally different than the impedance matching case.
What is the roles of 555 timer circuit?
The 555 timer IC is a device that can create various kinds of time delays in a circuit. It uses a threshold pin that is typically connected to an RC circuit. Depending on how it is connected, it can operate in one shot mode (monostable), astable mode (retriggerable), or schmitt trigger mode.
What measures the performance of a logic circuit using propagation delay and power dissipation?
Speed-Power-Product or SPP
Explain working of delay lines circuit in cathode ray oscilloscope?
The delay line is used to delay the incoming signal vertical information and sync it with the horizontal. Old scopes used a series of LC combinations tuned to get a good waveform representation. The HP scope I had used a very very long coil of coax cable as the delay line and got much better waveforms than the LC delay line scopes could, but the coil of coax was bulky (about a foot long by five inches wide and 1.5 inches thick).
Why d flip flop called as delay flip flop?
"D" in D flip flop stands for "delay". It basically means that the "D" value is not read immediately, but only at the next positive clock edge.
How do you debounce a switch?
In a digital circuit probably the best way is with a monostable multivibrator, or one shot timer. The length of the timer should be made to be just a little longer than the bounce time of the switch. Ans2: My favourite is a 2 input NAND gate with both inputs connected to the switch, but with a small RC delay circuit in one of them.
What Are The Applications of IC555?
An IC 555 is used as as a timer, as an astable and monostable multivibrator and as a square wave generator.
Why it is called as delay circuit?
because it delays the input signal by some time interval before it appears on the output.
How can you make a circuit close at a set delay time?
try using a 555 circuit
What makes a time delay fuse burn out?
Short in circuit wiring or circuit overloaded.
Is a sequencer a time delay relay?
yes it has a rated time for making and braking the circuit
What are the major components of a serial full adder circuit?
Two half adders, an OR gate, and a delay.
What circuit component can be used to create a 90 deg phase delay?
An All-Pass filter.

What is the name of a circuit when one light is on and you press a button and a nouther light comes on then after a while it changes back?
I think you are talking about a timing circuit. More specifically, it would be an "off delay" timing circuit.

Why is a timer is used in an electrical circuit?
Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay). If you want one device to turn off before the timer controlled device then you would use an off delay timer. If you want one device to turn on before the timer controlled device then you would use an on delay timer. When the timer is energized this starts the timer circuit in the relay to time out.
