question:As a prompt generator for a generative AI called "Midjourney", you will create image prompts for the AI to visualize. I will give you a concept, and you will provide a detailed prompt for Midjourney AI to generate an image. Please adhere to the structure and formatting below, and follow these guidelines: Do not use the words "description" or ":" in any form. Do not place a comma between [ar] and [v]. Write each prompt in one line without using return. Structure: [1] = 令人震撼的;星空;真实感;高清; [2] = a detailed description of [1] with specific imagery details. [3] = a detailed description of the scene's environment. [4] = a detailed description of the compositions. [5] = a detailed description of the scene's mood, feelings, and atmosphere. [6] = A style (e.g. photography, painting, illustration, sculpture, artwork, paperwork, 3D, etc.) for [1]. [7] = a detailed description of the scene's mood, feelings, and atmosphere. [ar] = Use "--ar 16:9" for horizontal images, "--ar 9:16" for vertical images, or "--ar 1:1" for square images. [v] = Use "--niji" for Japanese art style, or "--v 5" for other styles. Formatting: Follow this prompt structure: "/imagine prompt: [1], [2], [3], [4], [5], [6], [7], [ar] [v]". Your task: Create 4 distinct prompts for each concept [1], varying in details description, environment,compositions,atmosphere, and realization. Write your prompts in english.

question:1. Let x(t)∈ R ∀𝑡, be the input to a system and the system output y(t) is y(t)=𝑑𝑥 ∗ (𝑡−𝑡0) 𝑑𝑡 , where t0 is a constant. The spectrum of x(t) is known to be X(f). [40%] (a) Please show that the system is an LTI system. (15%)

answer:To show that the system is an LTI (Linear Time-Invariant) system, we need to demonstrate that it satisfies the properties of linearity and time invariance. 1. Linearity: The system is linear if it satisfies the property of superposition, which states that the response to a linear combination of inputs is equal to the linear combination of the individual responses to each input. Let x1(t) and x2(t) be two input signals, and let a1 and a2 be scalars. The corresponding outputs are y1(t) and y2(t). For the input signal a1*x1(t) + a2*x2(t), the output is given by: y(t) = d/dt [ (a1*x1(t) + a2*x2(t) - t0 ) / dt ] Expanding the above expression, we have: y(t) = a1 * d/dt [ (x1(t) - t0) / dt ] + a2 * d/dt [ (x2(t) - t0) / dt ] = a1 * y1(t) + a2 * y2(t) Therefore, the system satisfies the property of linearity. 2. Time Invariance: The system is time-invariant if a time shift in the input signal results in a corresponding time shift in the output signal. Let x(t-t0) be the input signal. The output is given by: y(t) = d/dt [ (x(t-t0) - t0) / dt ] Now, let's consider the input signal x(t-t0+a), where a is a constant representing the time shift. The output is given by: y(t-a) = d/dt [ (x(t-t0+a) - t0) / dt ] Comparing the two output expressions, we can observe that a time shift of 'a' in the input signal results in the same time shift 'a' in the output signal. Therefore, the system satisfies the property of time invariance. Since the system satisfies both the properties of linearity and time invariance, we can conclude that the given system is an LTI system.

answer:要显示系统是LTI(线性时不变)系统,我们需要证明其满足线性性和时不变性的属性。 1. 线性性: 如果系统满足叠加原理的性质,即对于输入的线性组合的响应等于每个输入的响应的线性组合,那么该系统就是线性的。 设x1(t)和x2(t)是两个输入信号,a1和a2是标量。对应的输出是y1(t)和y2(t)。对于输入信号a1*x1(t) + a2*x2(t),输出为: y(t) = d/dt [ (a1*x1(t) + a2*x2(t) - t0 ) / dt ] 展开上述表达式,我们有: y(t) = a1 * d/dt [ (x1(t) - t0) / dt ] + a2 * d/dt [ (x2(t) - t0) / dt ] = a1 * y1(t) + a2 * y2(t) 因此,该系统满足线性性的属性。 2. 时不变性: 如果输入信号的时间偏移导致输出信号的相应时间偏移,那么系统是时不变的。 设x(t-t0)是输入信号。输出为: y(t) = d/dt [ (x(t-t0) - t0) / dt ] 现在,让我们考虑输入信号x(t-t0+a),其中a是表示时间偏移的常数。输出为: y(t-a) = d/dt [ (x(t-t0+a) - t0) / dt ] 比较这两个输出表达式,我们可以观察到输入信号的时间偏移'a'导致输出信号的相应时间偏移'a'。因此,该系统满足时不变性的属性。 因为该系统满足线性性和时不变性的两个属性,我们可以得出结论,给定的系统是LTI系统。
