Digital Oscilloscope
A digital storage oscilloscope is an oscilloscope which stores and analyses the signal digitally rather than using analogue techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which they typically provide.[1]
The input analogue signal is sampled and then converted into a digital record of the amplitude of the signal at each sample time. The sampling frequency should be the Nyquist rate or better to avoid aliasing. These digital values are then turned back into an analogue signal for the display if this is a cathode ray tube (CRT) or otherwise transformed as needed for the various possible types of output.
The two types of D.S.O that we used were:
1: A High frequency wave generator
2: A Low frequency wave generator
• Resistance decade boxes
A resistance decade box or resistor substitution box is a unit containing resistors of many values, with one or more mechanical switches which allow any one of various discrete resistances offered by the box to be dialed in. Usually the resistance is accurate to high precision, ranging from laboratory/calibration grade accuracy of 20 parts per million, to field grade at 1%. Inexpensive boxes with lesser accuracy are also available. All types offer a convenient way of selecting and quickly changing a resistance in laboratory, experimental and development work without needing to attach resistors one by one, or even stock each value. The range of resistance provided, the maximum resolution, and the accuracy characterize the box. For example, one box offers resistances from 0 to 24 mega ohms, maximum resolution 0.1 ohm, accuracy 0.1%.
• Breadboard
A breadboard (proto board) is a construction base for prototyping of electronics. The term is commonly used to refer to solderless breadboard (plugboard).
Because the solderless breadboard does not require soldering, it is reusable. This makes it easy
