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).

How can you know whether chips are working or not?
A: For that you need an oscilloscope if dynamics are involved. Some success can be achieved if forced to a steady state and checking with a meter in-out
Identify two application of the chopper and explain how its work?
what is chopper explain its working principle
Explain the working principles of CRT briefly?
A Cathode Ray Tube is a specially constructed vacuum tube in which an electron beam controlled by electric or magnetic fields generates a visual display of input electrical signals on a fluorscent screen. It consists of three important parts, namely, an electron gun, a deflection system and a fluorscent screen.
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
Why is it important for the switch of the circuit to be open at the start of an activity?
If you mean by activity, working on an electrical circuit, then it is for safety reasons that a switch is opened. Most companies now use a proper lock out procedure so that everyone is aware that the circuit has been locked out. If more than one person is working on the circuit each person is required to have their own personal lock on the open switch.
Working principle of cathode ray oscilloscope?
A scope is nothing else then a display instrument it will amplify and display a signal on a CRT for visual analysis
What was Thompson working with when he discovered the cathode rays?
Thomson discovered cathode rays when he was working with electrons. He was performing experiments with the electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
What was JJ Thompson working with when he discovered the cathode rays?
Electrons.
Which subatomic particle was discovered to working with cathode-ray tubes?
electron
What is the flip flop draw the circuit diagrem of all flip flop and explain the working of flip flop using nor gates?
draw a logic circuit of the clocked SR flip-flop using NOR gate
Explain the construction and working of a CRO?
explain cro construction and working
If one outlet on a circuit is not working will the entire circuit not work?
No
How do you check a diode?
the diode will have two polarities anode and cathode .take multimeter and set it in buzer mode or resistance mode and connect the positive terminal of multimeter to anode of diode and negative to the cathode the multimeter shows the resistance say 500-700ohms if it working and doesn't show any impedance i.e, very high impedance in reverse bias i.e, by connecting the positive terminal of multimeter to cathode of diode and negative terminal to anode,and in no working condition it shows same characteristics as in reverse bias connected. the simple way of checking diode is connect the 2v led in series with the diode to the battery of 3v the led will glow if the diode is connected in forward bias in circuit and it doesn't glow if the diode is connected in reverse bias in circuit /diode is damaged . A: a diode will conduct from cathode [negative ] to anode [positive] A stripe at one end is the cathode or a stripe on the arrow is the cathode. By applying the proper voltage it will conduct and show low resistance and a voltage from .6v to .7v. Reversing the lead it will show relatively hi resistance.
How you check whether transistor working or not?
A: The only sure way is to use an oscilloscope. If you are well trained a meter can assist in fact finding.
When should you NOT wear a wrist band ground strap?
when working around an exposed cathode ray tube
What happens if a wire breaks?
The circuit stops working because of the short circuit
