Marvell India Interview Questions and Answers

Q1. Difference between latch and ff?
Ans. 
Latch is level sensitive and FF is edge sensitive. Latch is transparent while FF is opaque.
• Latch is level sensitive, meaning it changes output based on input level. FF is edge sensitive, changing output on clock edge.

• Latch is transparent, meaning output changes as soon as input changes. FF is opaque, output changes only on clock edge.

• Latch is faster but more prone to glitches. FF is slower but more stable.

• Examples: SR

Q2. Difference between blocking and non blocking assignments?
Ans. 
Blocking assignments wait for the assigned statement to complete before moving on, while non-blocking assignments allow for concurrent execution.
• Blocking assignments use '=' operator and execute sequentially.

• Non-blocking assignments use '<=' operator and allow for concurrent execution.

• Blocking assignments are used for combinational logic.

• Non-blocking assignments are used for sequential logic.

• Example: blocking assign...read more

Q4. What is ac and dc current
Ans. 
AC current alternates direction periodically, while DC current flows in one direction constantly.
• AC current changes direction periodically

• DC current flows in one direction constantly

• AC is used in household appliances, while DC is used in batteries

• AC is more efficient for long-distance power transmission

• DC is commonly used in electronics

Q5. What is frequency
Ans. 
Frequency refers to the number of occurrences of a repeating event per unit of time.
• Frequency is measured in Hertz (Hz), where 1 Hz is equal to 1 cycle per second.

• Higher frequency means more cycles per second, while lower frequency means fewer cycles per second.

• In electronics, frequency is used to describe the rate at which alternating current changes direction.

• For example, a frequency of 60 Hz means the current change

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

Basic questions not complicated need fundamental

Q1. What is resistance
Ans. 
Resistance is the opposition to the flow of electric current in a circuit.
• Resistance is measured in ohms (Ω).

• It is caused by collisions between electrons and atoms in a material.

• Higher resistance leads to lower current flow.

• Resistance can be controlled by changing the material, length, or cross-sectional area of a conductor.

• Examples of high resistance materials include rubber and glass, while copper and silver have low
