Filtering/edge detection, gradients, Laplacians, Sobel, Canny, etc. briefly what do each technique

(basic information). What do we mean for segmentation? Any example?

Which technique of the above provides better edge detection? Why?

What approach would you use to analyze a series/parallel AC circuit? How would you determine the magnitude and phase relationships for the voltages, currents, and powers in the circuit?

Preferred typed answer please.

Indirect detection systems and direct detection systems. What do we mean? (Bioinspired Vision Question)

explain in detail with diagrams what is corona effect and explain it's dis advantages briefly

3. Describe briefly how the primary equivalent T circuit is created in transformers and what physical quantities its elements represent.

------An analog signal is sampled, quantized, and encoded into a binary PCM wave. The number of representation levels used is 1024. A synchronizing pulse is added at the end of each code word representing a sample of the analog signal. The resulting PCM wave is transmitted over a channel of bandwidth 24kHz using a 8 PAM system with raised-cosine spectrum. The rolloff factor is 0.5.

(a) Find the rate (bit/s) at which information is transmitted through the channel.

(b) Find the rate at which the analog signal is sampled. What is the maximum possible value for the highest frequency component of the analog signal?

is using a 8 PAM system is different from using a quaternary PAM in this example ?????

thanks
