ELECTRONICS ENGINEERING JOB INTERVIEW QUESTIONS:- 1. What is an Amplifier? An electronic device or electrical circuit that is used to boost (amplify) the power, voltage or current of an applied signal. 2. What is Oscillator? An oscillator is a circuit that creates a waveform output from a direct current input. The two main types of oscillator are harmonic and relaxation. The harmonic oscillators have smooth curved waveforms, while relaxation oscillators have waveforms with sharp changes. 3. What is inductor? An inductor is a passive electrical device employed in electrical circuits for its property of inductance. An inductor can take many forms. 4. Distinguish between Angle modulation and Amplitude modulation. In amplitude Modulation as the amplitude of given signal varies, the amplitude of carrier signal also varies in the same way. In angle modulation, the frequency or phase may vary according to the amplitude of given signal 5. What is the basic difference between Latches and Flip flops? Latch works without clock signal,but works with a control signal and it is level triggered device.whereas flip flop is a 1 bit storage element and works with a clock signal.its a edge triggered device. normally latches are avoided and flip flops are preferred.
