Question

2) Design a modulator for a DSB-SC signal based on a squaring non-linear device, i.e. that has an input-output relation given by: $v_o(t) = v_i^2(t)$. You may use adders, filters, and carrier sources. Clearly, you may NOT use multipliers. a. Draw, and label appropriately, a block diagram of your modulator. a. Starting from the message signal show mathematically how your modulator produces the transmitted signal. Label the signals at the different points in your block diagram.

Step 1

Block diagram of the modulator: Message Signal (v_m) --> Squaring Non-linear Device --> Adder --> Carrier Signal (v_c) --> Filter --> Transmitted Signal (v_ot) b. Mathematically, the modulator can be described as follows: Show more…

Design a modulator for a DSB-SC signal based on a squaring non-linear device, i.e., that has an input-output relation given by: v_ot = v_it. You may use adders, filters, and carrier sources. Clearly, you may NOT use multipliers. a. Draw, and label appropriately, a block diagram of your modulator. b. Starting from the message signal, show mathematically how your modulator produces the transmitted signal. Label the signals at the different points in your block diagram.
