  1. Parallel digital data Team E K,J,H,Y.

  2. What is parallel digital data?k • digital data encoding scheme using multiple data pathways mainly used for binary representation.

  3. What is PDD used fork • Parallel and serial data transmission are most widely used data transfer techniques. Parallel transfer have been the preferred way for transfer data. But with serial data transmission we can achieve high speed and with some other advantages.

  4. Differences between serial and parallelk • In serial communication, data is send one bit at a time, running over a communication channel • Whereas Parallel transmits several streams of data simultaneously along multiple channels.

  5. Operational-amplifiersh • An op-amp can be connected to a single voltage rail (called unipolar supply) or a dual voltage rail (called bipolar supply). • When connected to a single voltage rail, the output can go from 0v to approximately full rail voltage. • Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices.

  6. How an Operational amplifier worksy • Op amps must always be supplied with DC power and therefore it is best to configure these connections first, before adding any other circuit components. • Op amps amplify tiny signals from sensors so analogue-to-digital converters (ADCs) can digitize them.

  7. Gainj • gain is a measure of the ability of a circuit which is usually in an amplifier • It is usually defined as the mean ratio of the signal output of a system to the signal input of the same system • In the following picture, the OP-AMP has a gain of 2. • For a gain of 2, the two resistors on the inverting input are EQUAL VALUE. The actual value of resistance is not important. It can be 10k to 100k, for example

  8. Negative feedbackj • Negative feedback occurs when the result of a process influences the operation of the process itself in such a way as to reduce changes. Negative feedback tends to make a system self-regulating it can produce stability and reduce the effect of fluctuations. • Negative feedback loops in which just the right amount of correction is applied in the most timely manner can be very stable, accurate, and responsive.
