Actual question papers, circuit design tasks, and VLSI tests shared by students who walked out of core EE 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?
