Renesas Electronics India Interview Questions, Process, and Tips

General aptitude questions. Easy to solve. Didn’t take much time

Q1. Explain operation of rc circuit
Ans. 
An RC circuit consists of a resistor and a capacitor connected in series or parallel, used for filtering, timing, and signal processing.
• RC circuit operation is based on the charging and discharging of the capacitor through the resistor.

• When a voltage is applied to the circuit, the capacitor charges up to the applied voltage through the resistor.

• The time constant (RC) determines how quickly the capacitor charges or disc...read more

Q2. Draw waveform for diode
Ans. 
A diode waveform typically shows a voltage drop when forward biased and no current flow when reverse biased.
• Forward biased: voltage drop across diode, current flows

• Reverse biased: no current flow, diode acts as open circuit

Q1. What is the difference between latch and flip flop
Ans. 
Latch is level triggered and stores data temporarily, while flip flop is edge triggered and stores data permanently.
• Latch is level triggered, while flip flop is edge triggered

• Latch stores data temporarily, while flip flop stores data permanently

• Latch requires continuous input to hold the output, while flip flop retains the output until a new input is received

Q2. Draw or gate using nand gates
Ans. 
A NAND gate can be used to create a NOR gate by connecting two NAND gates in series.
• Connect the outputs of two NAND gates together

• Connect the inputs of the two NAND gates to the same input signal

• The output of the combined NAND gates will act as a NOR gate

Q1. Designing of a frequency divider .
Ans. 
A frequency divider is a digital circuit that takes an input signal and produces an output signal with a frequency that is a fraction of the input frequency.
• Frequency dividers are commonly used in digital systems to generate clock signals at lower frequencies.

• They can be implemented using flip-flops, counters, or other digital logic elements.

• For example, a divide-by-2 frequency divider will output a signal with half th...read more

Q1. Designing of a edge detector
Ans. 
An edge detector is a circuit that detects transitions from one logic level to another in a digital signal.
• Utilizes flip-flops to store previous signal values

• Compares current signal value with previous value to detect edges

• Can be implemented using Verilog or VHDL

• Commonly used in digital signal processing applications
