The term pole in filter terminology refers to the feedback circuit. 2, A voltage shunt feedback with Ai-10, A-20, p 0.45, then Aif will be 1. 3. The integrator Op-Amp circuit can be used to produce square waves. 4. The equivalent circuit of the crystal oscillator is series and parallel (R, C) components. 5. The transistor in a class A power amplifier conducts for the entire input cycle. 6. Bypass capacitors in an amplifier determine the low and high-frequency responses. 7. The midrange voltage gain of an amplifier is 100. The input RC circuit has a lower critical frequency of 1 kHz. The actual voltage gain at f-100 Hz is 100. 8. The Bessel filter types produce almost ripple frequency response. 9. RC phase shift oscillators are based on both positive and negative feedback circuits. 10. In a high-pass filter, the roll-off region occurs above the critical frequency.arrow_forward

Define a function named feet_to_steps that takes a float as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. Then, write a main program that reads the number of feet walked as an input, calls function feet_to_steps) with the input as an argument, and outputs the number of steps. Use floating-point arithmetic to perform the conversion. Ex: If the input is: 150.5 the output is: 60 The program must define and call the following function: def feet_to_steps (user_feet) 646806.5094104.qx3zqy7…arrow_forwardREADING AND LISTENING ACTIVITIES BASED ON THE VIDEO: “REQUIREMENT ELICITATION “ Watch the following video and look for the answer to the following questions: https://www.youtube.com/watch?v=pSQRetBoaRE&t=24s 1.-NAME THE 2 PHASES OF THE REQUIREMENT ENGINEERING PROCESS 2.-NAME AT LEAST 7 ELICITATION TECHNIQUES TO COLLECT THE INFORMATION REQUIRED 3.-REFER TO THE NUMBER OF QUESTIONS AND TYPE OF QUESTIONS THAT SHOULD BE ASKED TO THE DIFFERENT STAKEHOLDERS. 4.-NAME THE DIFFERENT TYPES OF PROBLEMS YOU CAN ENCOUNTER DURING THE REQUIREMENT ELICITATION PROCESS 5.- ACCORDING TO THE VIDEO, WHICH TYPES OF TECHNIQUES SHOULD YOU USE, WHICH ONES WOULD YOU USE ACCORDING TO PROFESSOR SHERRIFF ‘S RECOMMENDATIONS?arrow_forward

The ground surface is loaded with heavy construction machinery applying a pressure of q = 10.0 kPa. Other data is according to the figure.Assume the sheet pile moves sufficiently to the left to reach active failure conditions behind it, and passive failure conditions develop in the soil mass below the excavation bottom. Will the sheet pile wall hold without rain? (Calculate the forces.) Will the sheet pile wall hold if it rains? (Assume water-filled cracks.) If the sheet pile does not hold in any of the above cases – how deep would it need to be embedded in order to hold?
