Extraordinary growth in wearables is being seen post covid years, covid alone is not the main reason. Major chunk of gadget friendly population were buying wearble for health monitoring even before covid. It's not just gadget crazy people buying wearable devices, even the cost conscious ordinary buyer thinking of investing in a wearable device for the benefits it gives. It saves time in monitoring health of aged person and sick person at home remotely.
The cost and pain of hospitalisation is driving the fear among health-conscious people to give importance to preventive healthcare and t...
In the previous module we have studied on the electrical properties of audio signal. In the world of digital electronics, the semiconductor logic and processing devices does not compute without digitizing the analog signal. A semiconductor device called analog to digital converter is used to convert linearly varying analog-flow into multi-bit digital binary numbers of where constant output voltage of 5V/3.3V is binary number 1 and zero voltage is binary number 0, representing amplitude quantity of analog signal. To give an example, a 6 volt measuring analog signal can have 8-bit binary out...

Flash memory basics and its interface to a processor:
Introduction:
Flash memory or a flash RAM is a type of nonvolatile semiconductor memory device where stored data exists even when memory device is not electrically powered. It's an improved version of electrically erasable programmable read-only memory (EEPROM). The difference between Flash Memory and EEPROM are, EEPROM erases and rewrite its content one byte at a time or in other words, at byte level. Where as Flash memory erases or...
