A- Select the best answer from multiple choices: 1. N messages, each band limited wo are to be transmitted over a common channel. This can be achieved using: a-FDM b-TDM C-FDM as well as TDM d- Neither FDM nor TDM 2. A signal x(t) with dynamic range + 4 volts is sampled and quantised using a 3 bit analogue-to-digital convertor (ADC). The quantisation step size is : a. 2 volts b. 1 volts c. 0.5 volts d.0.2 volts. 3. There is a need to send a pulse wave with a minimum requirements, then we use: a.FSK b.ASK. c.PSK. d.all the above can be used.
