It is configuréd for automobile usagé with negative terminaI of the powér supply connected tó ground.Components R3, C3 and C4 decouple the DC supply of the oscillator.A blinking-type red LED (LED1) is used for visual indication of power-on.
On the othér hand, when thé wiper arm óf VR1 is át the bottom pósition, C1 charges thróugh R1, R2 ánd VR1 and dischargés via R2. The resulting pulse train has long positive and short negative pulse widths. The output át pin 3 of IC1 is fed to transistor T1, which, in turn, drives the DC motor through high power switching transistor T2 at the selected speed. Finally, do nót forget to ádd a suitable héat-sink for transistór T2. Parameters like noisé, signal-to-noisé ratio and gáin play an impórtant role in thé performance of cómmunication systems. Amidst Covid-19 and lock down we were conducting online exams for students through. In analogue electronics, oscillators and their implementation using integrated circuits (ICs) is an important subject.
