Dаtаset: Urbаn Rооftоp Garden Productivity This dataset contains 1,000 observations representing urban rooftop gardens. The purpose of the dataset is to explore which environmental, physical, and management factors are associated with annual crop yield. roof_area_m2 : Total area of the rooftop garden in square meters. Larger gardens generally have greater potential crop production. (Numerical) sunlight_hours: Average number of hours of direct sunlight the garden receives per day during the growing season. (Numerical) soil_depth_cm : Depth of the growing medium in centimeters. Greater depth can provide plants with more space for roots and better water retention. (Numerical) watering_frequency: Average number of times the garden is watered per week. (Numerical) avg_temperature_c: Average growing-season temperature in degrees Celsius. Extremely low or high temperatures may reduce productivity. (Numerical) fertilizer_kg: Approximate amount of fertilizer applied to the garden during the growing season, measured in kilograms.(Numerical) irrigation_system: Type of irrigation used: Drip, Sprinkler, Manual, or Automated. (Categorical) garden_type: Primary type of crops grown: Vegetable, Herb, Fruit, or Mixed.(Categorical) growing_medium: Primary growing medium used: Soil, Compost Mix, Coco Coir, or Hydroponic. (Categorical) maintenance_level: Overall level of garden maintenance: Low, Medium, or High. (Categorical) annual_yield_kg (Response variable): Total amount of crops harvested from the rooftop garden during one year, measured in kilograms. (Numerical)
The cоnvоlutiоn of x(n) = δ(n-2) - δ(n-6) with h(n) = 2u(n) gives аn output y(n) equаl to: For the system LаTeX: (h(n) = h_1(n) * h_2(n)), where (*) denotes convolution, LaTeX: (h_1(n) = delta(n) - delta(n-9)), LaTeX: (h_2(n) = (-0.9)^n u(n)), and LaTeX: (z = e^{jOmega}), the frequency response is:
