Is it possible to protect the environment when many countries require increasing amounts of energy to boost economic progress? According to Alan M. Eddison‚ “Modern technology owes ecology an apology.” This is definitely true as economies and technologies have developed recklessly at the expense of the environment. The world has seen huge increases in consumption of the Earth’s scarce resources ever since the Industrial Revolution in the 1800s and countries‚ especially the developed countries

is undefined. The TTL standards came a long time after the RS232 standard was set. Due to this reason RS232 voltage levels are not compatible with TTL logic. Therefore‚ while connecting an RS232 to microcontroller system‚ a voltage converter is required. This converter converts the microcontroller output level to the RS232 voltage levels‚ and vice versa. IC MAX232‚ also known as line driver‚ is very commonly used for this purpose. The simplest connection between a PC and microcontroller requires

CHAPTER 7 1. The ability of a receiver to choose a desired signal frequency while rejecting closely adjacent signal frequencies is known as selectivity. 2. Decreasing the Q of a resonant circuit causes its bandwidth to increase. 3. Good selectivity usually means narrow bandwidth. 4. True. A tuned circuit can provide voltage gain. 5. Cascading tuned circuits cause the selectivity to increase. 6. If the selectivity of a tuned circuit is too sharp‚ the sidebands of the received signal
