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.
Consider the basic MOSFET circuit shown in Figure with variable gate voltage. The MOSFET is given to have very large V A , V T = 4V,and I DSS = 8 mA. Determine i D and v DS for
The increase in the current is building up the magnetic field surrounding the coil. Energy is stored in that field. Consider the energy supplied by the voltage source during the
Explain protected mode interrupt. In this mode, interrupts have exactly similar assignments as in real mode, but the interrupt vector table is not same. In place of interrupt
Inductive Logic Programming : Now here having studied a non-symbolic approach to machine learning on Artificial Neural Networks then we return to a logical approach, namely In
What is the main thing to look for in calculations of air gaps?
At what velocity must a conductor 75 mm long cut a magnetic field of flux density 0.6 T if an e.m.f. of 9 V is to be induced in it? Suppose the conductor, the field and the directi
I want to know latest optimization technique and algorithm for modal reduction and pid controller design
Q. Give the principle of biasing a FET amplifier. To correctly bias the FET, the gate needs to be negative with respect to the source. Bias is obtained in the following manner:
NOP No Operation Instruction No operation is performed when this instruction is executed. The instruction format is NOP All registers and flags re
Design a circuit using op-amp that will reject the 60kHz power line noise and also reject high signal frequency above 800Khz. The stop-band width around the 60kHz centre frequency
