This problem was solved by Dolph in 1946. He derives a method for obtaining weights for uniformly spaced linear arrays steered to broadside (=90 degrees). This is a popular weighting method because the sidelobe level can be specified, and the minimum possible null-null beamwidth is obtained.
Some differences is that: Photography can form a picture in seconds, where as a painting can take months to create. Also, photography is a cheaper, and also, you can make sooo many images of the same photo via the negatives. Paintings have only One, unless the artist is bothered to paint the exact same painiting! lol.
2 months ago. 1  DIGITAL VS CONVENTIONAL. I think that digital photography is a tad bit better considering speed however, it does not matter which you use. 2  Digital vs Film. I think Digital is better practically because itâs more faster & easier to use because Film images are processed by the Lab. I believe that both digital and film photography are the equal because they produce the same quality. I do believe, however, that digital photography is faster.
