Master core EE subjects for interviews and exams. Our questions cover Digital Logic, VLSI, Power Systems, and more, helping you prepare for both university tests and technical job interviews.
Explain the concept of Quadrature Amplitude Modulation (QAM).
Convert the hexadecimal number 2B to its decimal equivalent.
An ideal diode is used in a half-wave rectifier with a sinusoidal input of 10V peak. What is the DC average voltage of the output?
A BJT switch has Vcc=10V, Rc=10kΩ. If Vce(sat)=0.2V, what is the maximum possible collector current?
What is the main advantage of CMOS logic over TTL or NMOS logic families?
In a common-emitter BJT amplifier, the collector current (Ic) is 2mA and the current gain (β) is 100. Calculate the base current (Ib).
Differentiate between Moore and Mealy state machines.
What is VSWR (Voltage Standing Wave Ratio) and what does a VSWR of 1:1 signify?
Use De Morgan's theorem to find the equivalent of NOT(A AND B).
Define poles and zeros and explain their significance in system stability.
You need to create a -3.3V supply from a +5V rail. Which DC-DC converter topology should you choose?
Differentiate between active and passive filters.
What is an interrupt service routine (ISR)?
What is Direct Memory Access (DMA)?
What is the function of a decoder in digital logic?
