Figure (1) shows that the 566 contains current sources to charge and discharge an external capacitor C1 at a rate set by external resistor R1 and the control dc input voltage. A Schmitttrigger circuit is used to switch the current sources between charging and discharging the capacitor‚ and the triangular voltage developed across the capacitor and square wave from the Schmitt trigger are provided

DEFINITION: An amplifier with two or more stages arranged in a manner that the output of one serves as the input for the next‚ while amplifying at each step. It is also called cascade amplifier. EXPLANATION: In most of the cases the gain provided by a single stage amplifier stage is insufficient. Consequently two or more amplifier stages are cascaded in order to increase the gain. Several amplifiers can be connected in a cascaded arrangement with the output of one amplifier driving the input of the

Chapter 1 Introduction 1.1 Introduction: Wireless communication has announced its arrival on big stage and the world is going mobile. We want to control everything and without moving an inch. This remote control of appliances is possible through Embedded Systems. The use of “Embedded System in Communication” has given rise to many interesting applications that ensures comfort and safety to human life. The project mainly focuses on transmission of textual data through air interface by the use

between these three components is what allows defibrillators to effectively restore proper cardiac rhythms. I.) Capacitors: One of the key components of a defibrillator is a capacitor. The capacitor of a defibrillator stores a large amount of energy in the form of electrical charge. Then‚ over a short period of time‚ the capacitor releases the stored energy. The capacitor itself contains numerous components: a pair of metal plate conductors and an insulator. The insulator is in the middle

The amplified signal from the preamplifier stage is fed to input pin 3 of IC LM386N (IC1) through capacitor C2 (100nF) and volume control VR1 (10-kilo-ohm log). A decoupling network comprising resistor R5 and capacitor C3 provides the preamplifier block with a clean supply voltage. Audio amplifier IC LM386N (IC1) is designed for operation with power supplies in the 4-15V DC range. Circuit diagram: spy
