Consider the following statements regarding Differential Pulse-Code Modulators (DPCM): 1. The differential pulse-code modulator system employs a predictor. 2. It needs far fewer bits per each error sample than what would have been needed for the original samples themselves. 3. It will have a larger dynamic range than the original message itself. Select the correct statements using the code given below:

Consider the following statements regarding amplitude modulation and choose the correct option: Statement A: Amplitude modulated waves can be produced by application of the message signal and the carrier wave to a non-linear device, followed by a band pass filter. Statement B: For a sinusoidal message signal, an amplitude modulated wave contains frequencies ωm, 2ωm and ωc, each of the same amplitude.
