Given a battery rated at 10 amp-hours, how long could my differential amplifier (containing a circuit of three (3) 741 op amps) be powered by the battery, before the battery would fully discharge.
A) Design a low-pass filter with a cutoff frequency of 12 kHz. Use 0.15 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at a frequency of 20 kHz Give your answer both as ratio (Vout/Vin) an..
we know Ktw=1 Nm(rad/s) and its's rated torque 30Nm for the synchronous frequency 60 H. If this motor is running at 60Hz, its load torque changes from 30 to 10 Nm, what is the new motor speed.
A continuous time system, described by y(t) = 5 Cos (2*pi*20*t + pi/2), is sampled at a rate 320 Hz. (a) Write the mathematical expression that describes the discrete time (sampled) signal. (b) Calculate the value of the discrete signal for n = ..
