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.
A coil of inductance 0.04 H and resistance 10? is connected to a 120 V, d.c. supply. Verify (a) The final value of current (b) The time constant of the circuit (c)

The system diagram for the proposed unit is shown below. The system operates on the principle of Time to Rate Conversion. Signals from the heart beat sensor are amplified
The pre-processing unit is responsible for taking the conditioned output from the heart sensor and generating a binary count during time T1 of this waveform (datain). It will compr
Q. Explain Continuous-data and discrete-data systems? A continuous-data system is one in which the signals at various parts of the systemare all functions of the continuous-tim
You are given a binary image consisting of only zeros and ones, see image-A. Apply required morphological operations and give the output images on the grid.
Q. Antinoise Systems — Noise Cancellation? Traditionally sound-absorbing materials have been used quite effectively to reduce noise levels in aircraft, amphitheaters, and other
Q . Why CE Configuration is widely used in amplifier circuit? The main utility of a transistor lies in its ability to amplify weak signals. The transistor alone cannot perform
