Morse code is a method of transmitting textual information as a series of on-off tones, lights or clicks that can be directly understood by a trained listener without using any special equipment. The International Morse Code encodes alphabets, numerals and a small set of punctuation and procedural signals as standardised sequences of short and long signals called ‘dots’ and ‘dashes,’ respectively.
An instrumentation engineer slips into a variety of roles, be it designing, developing, managing, installing or marketing, and is often employed across various industries. In India, the jobs available in instrumentation are more focused on sales and marketing as well as IT industry. Let us take a look at the scope for a career in instrumentation in India, the kind of opportunities available and the pay it offers
Here we put all the theory to work and present a simple power amplifier module that can be easily built with readily available components. The block diagram of the amplifier is shown in Fig. 1. It is typical of most audio amplifiers, although the circuit is somewhat different.
Automatic headlamps are the latest convenience in today’s cars. These eliminate the need for the driver to manually switch on or switch off the headlamps in most driving situations. The automatic headlight system reacts like the human eye to outside light levels and independently turns the lights on and off when needed. Such a system offers both safety and convenience.
The regular 16×2 LCD can display characters of only certain dimensions. A graphical LCD (GLCD), on the other hand, can display custom graphics. GLCDs are therefore highly suitable for mobile and industrial applications.
Most square-wave generators have a single output that doesn’t have a high driving capability/slew rate or is not adjustable in the required amplitude range. Also, when conducting experiments or testing the electronic equipment, the errors are frequent and there is a high probability of damage to the digital generator output.
gEDA offers a very mature suite of free software packages for complete project design cycle. However, there are three main roadblocks to the success of gEDA—use of Linux platform, discontinued gEDA manager development and documentation not being very recent. Here we discuss ways to overcome these hassles
