MediaTek India Technology Interview Questions, Process, and Tips

TDMA, CDMA, WCDMA, and OFDM are different multiple access techniques used in communication systems.

• TDMA (Time Division Multiple Access) divides the available frequency into time slots.

• CDMA (Code Division Multiple Access) uses unique codes to differentiate between users.

• WCDMA (Wideband Code Division Multiple Access) is an advanced version of CDMA.

• OFDM (Orthogonal Frequency Division Multiplexing) divides the available fr...read more

Burst errors can be detected and corrected using error detection and correction codes.

• Use error detection codes like CRC (Cyclic Redundancy Check) to detect burst errors

• Use error correction codes like Reed-Solomon codes to correct burst errors

• Re-transmit the data if the error cannot be corrected

• Implement error detection and correction algorithms in the communication protocol or data storage system

CMOS inverter is a digital logic gate that converts input signal to its complementary output signal.

• CMOS inverter consists of a PMOS and an NMOS transistor connected in series.

• When input is high, PMOS is off and NMOS is on, output is low.

• When input is low, PMOS is on and NMOS is off, output is high.

• Body bias effect is the change in threshold voltage of MOSFET due to variation in body voltage.

• MOSFET is preferred over BJ...read more
