What is the working principle of RAMP type digital voltmeter?
The working principle of ramp type digital voltmeter is that: It takes measurement of the time that is taken by instrument for its input voltage to change its state from input level to zero level and also the reverse is also true. An digital counter is employed in this system that measured time intervals and gives this output to the display unit that merely displays the output inform of digits with the help of indicating tubes thus making this section to work as output device. A voltage, referred as ramp voltage, is initiated at the beginning of measurements. Generally used ramp is negative going type but we also use one of positive going type. A continuous comparison is made between ramp voltage and that the voltage under measurement. As soon as, it is found that ramp voltage becomes equal to the input voltage a pulse in formed by coincidence generally called comparator circuit. At the same time value of ramp voltage is also made to fall down till the time when it reaches zero level. When value of ramp voltage has fallen to zero or ground another circuit called ground comparator comes into play and result in to close the gate. Some time is taken by the circuit between opening and closing of the gate can be given by T, now, clock pulse generator circuit generates some pulses during time T that are given to gate as a result of them counting an displaying can be performed. Thus, Input voltage that was initially fed to the instrument is read in digital form. It employs multi-vibrator circuits that are basically used to determine rate according to which cycles of measurement are started this multi-vibrator is called sample rate multi-vibrator. It is because the initial pulses that are responsible for activation or generation of next ramp voltages are generated by sample rate multi-vibrator as with as multi-vibrator also sends a pulse to counter circuit that makes it to come again to 0 states to clean up the digital display.
Design principles of function generator?
A: A function generator do just that output a function from any input. It can be as simple as sine wave, square wave, sawtooth, and ramp generator principle is to provide amplifiers that the output are gated to limits allows sum and subtract the input to provide the desired function. It looks more like an analogue computer when finished if it is very complex in design.
What is the applications of sawtooth generator?
The main application of a sawtooth generator in consumer electronics has been in CRT displays. To control the scanning of the electron beam, you need precise ramp input to the deflector coils, but you need to bring back the electron beam to the left side (top) of the display quickly to maximize brightness; hence, two sawtooth generators for the vertical and horizontal scanning. Of course, this is less common than it once was, since the advent of LCD and plasma displays.
What will happen if dc voltage is applied to anop amp integrator circuit?
Just consider the a DC voltage as the function y = (DC value), lets call the DC value 1 volt. Then the integral of y=1 is y=x. The op amp will create a ramp that is representative of y=x until it saturates. Depending on the op amp, it will most likely saturate somewhere around Vcc - 2V. As soon as it hits this rail it will level off.
What is horizontal deflection system in CRO?
in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically. For that purpose a horizontal deflection plate is provided in the cro. This deflection plate is supplied with voltages , so that the electrons passing through these plates get deflected horizontally.due to alternating voltages these electrons deflect right & left very quickly, that we humans fell it is a straight horizontal line due our perception. THE voltages is provided by sweep generator,which produce ramp voltages WHICH IS AMPLIFIED & PROVIDED TO HORIZONTAL DEFLECTION PLATES in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically.

What is a straight stair?
A ramp
Where can I find instructions for building stair ramps?
Ramp Solutions offers severel ways to build stair ramps and a place to get the materials. You could learn everything you need to know about stair ramps from one website.
How does a ramp digital multimeter operates?
A ramp digital multimeter operates by generating a linear voltage ramp that is applied to the input signal. The multimeter measures the time it takes for the ramp voltage to match the input voltage, which is then converted into a digital reading. This method allows for accurate and fast measurements of voltage, current, and resistance. Additionally, ramp multimeters often feature high precision and can capture transient signals effectively.
Examples of inclined planes?
It can be ramps, stair rails, path up hills, slides,slanted roads,stairs.........go on google.......there will be really helpful things.
What is safer falling down a ramp or falling down the stair?
I would say a ramp because there is no sharp corners to hurt yourself with, Personally avoiding the fall all together might be your best bet.
What happened to stair number 898 in the Washington Monument?
Conversion to a wheelchair ramp is what happened to stair number 898 in the Washington Monument. Because of the conversion, the monument now has only 897 steps between the bottom and the top.
What is the working principle of digital voltmeter?
# voltmeters usually employ an electronic circuit that acts as an http://www.answers.com/topic/integrator, # linearly ramping output voltage when input voltage is constant (this can be easily realized with an http://www.answers.com/topic/operational-amplifier). # The dual-slope integrator method applies a known reference voltage to the integrator for a fixed time to ramp the integrator's output voltage up, then the unknown voltage is applied to ramp it back down, and the time to ramp output voltage down to zero is recorded (realized in an http://www.answers.com/topic/analog-to-digital-converter implementation). # The unknown voltage being measured is the product of the voltage reference and the ramp-up time divided by the ramp-down time. # The voltage reference must remain constant during the ramp-up time, which may be difficult due to supply voltage and temperature variations. . Digital voltmeters necessarily have input amplifiers, and, like vacuum tube voltmeters, generally have a constant input resistance of 10 megohms regardless of set measurement range

How you could use a simple machine to move a piano up a five foot-high stair?
You could use a ramp as a simple machine to move the piano up the stairs. By tilting the ramp against the stairs at a gentle angle, you can roll the piano up the ramp instead of lifting it directly. This reduces the force needed to move the piano and makes it easier to transport up the stairs.
What does gangway have to do with the navy?
Ships tie up to piers and wharfs. There needs to be a way to get from the ship to the shore. This is normally provided by a gangway, a platform/stair/ramp used for movement between the two.
A ramp is 1.0 m high and 3.0 m long. What is the IMA of the ramp?
The ideal mechanical advantage (IMA) of a ramp is calculated by dividing the length of the ramp by its vertical height. In this case, the IMA would be 3.0 m / 1.0 m = 3.0.
