You are the new chief PCB designer for a small company who are about to become heavily involved in the design and realisation of digital timing products. Your management wants to prove the path from design entry to final design data production. Consequently, your first task within the company is to take a design from concept through to completion. Given the nature of the company business, it has been decided the test design will be a digital clock, the block diagram of which is illustrated below. An additional requirement is miniaturisation and the board size should be as small as is practically possible.
Each of the elements can be realised from 7400-series TTL in SMD packages. The circuit below shows the internal components and connections for the divide-by-60 block above. The counters are 74160 and the 7-segment BCD is a 7447. Any additional information is readily available in data books and the internet.
Q. Explain state-variable techniques? The matrix formulations associated with state-variable techniques have largely replaced the block-diagram formulations. Computer software
8086 is having 2 dissimilar units i.e. BIU(Bus Interface Unit) and EU(Execution Unit), these two units work synchronously.
Explain the principle of a thermocouple. Give two examples of some common thermocouples. Thermocouples : They are used for the measurement of temperature. While two wires of v
in case of a differentiator will the amplitude rise or falls?
Schottky diodes The schottky diodes have very fast recovery time and low forward drop. The current ratings of these diodes vary from 1A to 300 a and maximum allowable
Define the term Causality LTI System Any practical LTI system operating in real time must be "causal" which means that its impulse response {h[n]} must satisfy h[n] = 0 for n
I want project ideas.
Q A residence is supplied with a voltage v(t) = 110√2cos120πt Vand a current i(t) = 10√2cos120πt A. If an electricmeter is used tomeasure the average power, find the meter reading,
Using the LM741operational amplifier build a current amplifier with the voltage gain of |A V | = 300 v/v ± = 20% . Measure all necessary parameters of the amplifier (as per delive
