Pole-zero cancellation reduces pile-up artifacts that may occur when you are measuring many pulses and using a preamplifier (like in a radiation counting system).
The pole-zero cancellation is essentially an extra network of resistors that will eliminate the undershoot that you would normally see in the output of a preamp. When undershoot occurs, you end up with another "pole" in the denominator of the transfer function, so adding in the extra resistor network will "cancel the pole" in the denominator.

What is the interlace in pole and zero?
its nothing but alternate occurence of pole/zero and zero/pole. ex: f(s)=s*(s+2)/(s+1). here we can easily sense that there is a occurence of zero(s=0),pole(s=-1),zero(s=-2).
Why is absolute zero important?
absolute zero is the essence of nothing and nothing is a quantity of zero.
What does dp and sp mean on a socket?
Double pole and single pole.
What is differene between 2 pole 4 pole electric motor?
A 2-Pole motor runs twice as fast as a 4-pole motor. The 2-pole motor has 2 windings at 180 degrees apart and the four pole motor has four windings at 90 degrees apart. The rotor tries to move from pole to pole with each half cycle of the AC current so the motor no-load speed for 60 cycle current is 2x3600/#poles. This is 1800 rpm for a 4-cycle motor and 3600 rpm for a 2-pole motor.
What would cause a lighting contactor to hum vigorously?
The first thing that springs to mind is that the pole faces of the contactor are dirty. If the contactor is in a position where it can get weathered, it would probably be a rust built up. Dis assemble the contactor and emery cloth the pole faces until they are shiny again. A light wiping of oil will increase the time between cleanings. If the sound is more like a chatter then the shading coil on the contactor's pole face could be cracked or broken. This small copper coil is used to induce magnetism into the pole face to hold the contactor closed as the voltage transits through the zero voltage of the sine wave cycle.

What is the diameter of geographic North Pole?
The exact diameter of the geographic north pole (like the south pole) is in theory zero.
What is the average amount of rain in the north pole?
zero
Distance from the international date line and the north pole?
The distance is zero. The north pole is one end of the International Dateline. The south pole is the other end.
What are example of 3 reference points that are stationary relative to Earth?
North Pole, South Pole, and the zero-zero point (where the equator passes through the Greenwhich Meridian.)
What is the minimum and maximum degrees measured in latitude?
Latitudes range from zero to 90 degrees.The equator is the line of zero latitude.The north pole is 90 degrees north latitude.The south pole is 90 degrees south latitude.
How many degrees of latitude are there from zero degrees latitude to the north pole?
There are 90 degrees of latitude from the equator (0 degrees latitude) to the North Pole (90 degrees latitude).
To the nearest million how many penguins were at the North Pole in 1995?
Zero. Penguins do not live at the North pole. They live in the Antarctic.
What are the latitudes of the equator and the poles?
Equator . . . zero latitudeNorth pole . . . 90° North latitudeSouth pole . . . 90° South latitude
How many degrees of latitude between north and south pole?
Latitudes range from zero at the equator to 90° N at the north pole, and from zero at the equator to 90° S at the south pole. That's a total of 180° from one pole to the other ... exactly as you'd expect for a trip half-way around the globe.
Yearly rainfall at the south pole?
Zero. Water would freeze.
What is the largest measurement of latitude and longitude?
-- Latitudes range from zero at the equator to 90° N at the north pole, and from zero at the equator to 90° S at the south pole. -- Longitudes range from zero to the Prime Meridian, east and west to 180° in the middle of the Pacific Ocean.
