The block that is NOT present in a PCM Transmitter

• Low Pass Filter

• Sampler

• Encoder

• Amplifier

The difference between the actual analog value and approximated discrete value due to the rounding is called

• Quantization Error

• Sampling Error

• Reading Error

• Actual Error

Each quantized sample is assigned the binary code that represents the discrete amplitude value closest to the pulse's actual value. This is known as

• Encoding

• Sampling

• Quantizing

• Decoding
