The process of a unity-feedback control system has the transfer function100Gp(s) = ------------------------s^2 + 10 s + 100
Design a series controller (a PD, PI or PID) so that the following performance specifications are satisfied.
Steady-state error due to a step input = 0Maximum overshoot < 2 percentRise time < 0.02 second
Carry out the design in the frequency domain and check the design in the time domain.
Zener diode, Can You show me how to solve the following: If a 5k resitor is connected between the cathode of a 6.2V ZENER diode and a 12V power supply.
Digitizing an Audio Signal, PAM, ADC, An audio signal has a bandwidth that extends from 100 Hz to 10 kHz. The signal is sampled to create a PAM signal and then digitized by an analog to digital converter (ADC) that has 8 bits.
Draw the per-phase impedance diagram of the power system and Draw the impedance diagram in per-unit system
Ziegler-Nichols Open Loop Tuning Often, when working with a faster loop, many people will opt only for a PI control philosophy
What would be the initial value of v c (t) when switch is closed and determine the time constants in both cases (switch is open, switch is closed).
Tune PI Parameters, Question: Given are the facts that Gc and Gp(s) are in series and Gp(s) = (K * Km) / [s[(Ls+R)(Js+b) + K^2m)]].
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
What are the essential features of an ideal op amp? Identify the terminals of an op amp. Draw its equivalent circuit. Define virtual ground and what is difference amplifier? Draw its circuit. Define C.M.R.R.
To understand dierent signal models To be able to model a discrete-time system and design simple signal processing algorithms.
A 1 kHz sine wave signal with a power level -10 dBm is applied to the input of the amplifier. What is the power at the amplifier output?
Output levels of higher order products of a linear amplifier, If a tone is put into an amplifier, and its amplitude is increased by 1 dB, how much will the amplitude of the third-order products increase in dB?
