The pattern obtained when two sine waves having different frequencies are applied to the vertical and horizontal inputs of an oscilloscope is called: Correct Answer Lissajous figures

  • When horizontal deflection plates and vertical deflection plates of CRO (Cathode Ray Oscilloscope) are connected to two sinusoidal voltages, the patterns appear at the CRO screen are called the Lissajous pattern.
  • The Lissajous pattern obtained in a CRO depends upon frequency, amplitude, and phase relationship.

Additional Information:

The Lissajous pattern obtained for constant frequency and amplitude but with different phase angle is as shown:

The linear sweep for the time base in an oscilloscope has deviation from its nominal waveform. The nominal (dashed line) and actual (solid line) sweep waveforms are shown in the following figure. A 5 V p-p sine wave with a frequency of 1 kHz will be measured on the oscilloscope as a sine wave with
Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. Earthquakes are the shaking and moving of the ground when energy is released in waves.   P. These waves are similar to ocean waves, which move through water. Q. These waves are called seismic waves.  R. Seismic waves, however, move through the ground. S. Earthquakes can also be caused by other natural events, such as landslides and volcanoes.  6. Manmade earthquakes happen because of nuclear testing and mining explosions.

An oscilloscope is powered from 230 V mains having a nominal frequency of nearly 50 Hz. The triggering mode of the oscilloscope is set to LINE. A square wave from a function generator is fed to the Y input and a stable display (properly triggered) is obtained when the frequency of the function generator is 297 Hz. The actual frequency of the power supply is
