B)performs better when interference is present
C)more power is required to transmit
D)frequency and phase changes occur continuously

Digital modulation makes better use of the available spectrum as it allows for more efficient use of bandwidth by allowing multiple signals to occupy the same frequency range through techniques such as CDMA. Digital modulation also performs better in the presence of interference by using error correction codes and modulation schemes that are less susceptible to noise and distortion. However, digital modulation does not require more power to transmit and frequency and phase changes occur discretely, not continuously, so option C and D are incorrect.
