Introduction to DC to DC Converter

Buck Boost Converter The buck boost converter is a DC to DC converter . The output voltage of the DC to DC converter is less than or greater than the input voltage. The output voltage of the magnitude depends on the duty cycle. These converters are also known as the step up and step down transformers and these names are coming from the analogous step up and step down transformer . ...

Introduction to Quartz Clock:How Digital Watch Works!!

Quartz Clock or Digital Watch: Inside a quartz clock or watch, the battery sends electricity to the quartz crystal through an electronic circuit. The quartz crystal oscillates (vibrates back and forth) at a precise frequency: exactly 32768 times each second. The circuit counts the number of vibrations and uses them to generate regular electric pulses, one per second. ...

Signals Basics

Signals A gesture, action, or sound that is used to convey information or instructions, typically by prearrangement between the parties concerned. What is Amplitude??? T he maximum difference of an alternating electric current or potential from the average value. What is Frequancy??? Frequency is the number of occurrences of a repeating event per unit of time . T he rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light). ...
