Design a circuit that takes a sinusoidal input of varying frequency at 1V amplitude and produces an output amplitude of approximately 1V when the frequency is 1 Hz and approximately 0.5V when the frequency is 1,000Hz. Choose real component values to get as close as possible to the specified amplitudes.
A unity feedback control systems for a robot submarine has a plant with a third-order transfer function G(s) = K / (s(s + 10)(s +50)) We want the overshoot to be approximately 7.5% for a step input
A simple voltmeter with a full-scale reading of 50(V) is required. Use a d'Arsonval movement with a rating of 20(mV) at 1 (mA). Calculate the value of the voltmeter resistor, Rv, required to achieve these design specifications.
What are the distinguishing features of the response in the pass-band? What are the distinguishing features of the response in the stop-band? What is an all pass filter?
Find the equivalent impedance for Z1 = 60 L+60 and Z2 = 80 L-45 when these are connected in parallel What are the branch currents and the total circuit current if the supply voltage to the circuit is VS = 240V L0
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 in dBW?
b) What are the equilibrium electron and hole concentrations at 300K and 500K (hint: You will have to find Nc and Nv at 500K, but it isnt necessary for 300K) c) Why does the mobile carrier concentration increase at high temperatures
Analog to Digital Converters The input signals of an (10bits) ADC are from -1Volt to +1Volt. a) What is the rage of the converters b) What is the resolution c) What is the precision What is the value the minimal input signal variation that this ADC c..

if Eb the energy per bit of a binary digital signal, is 10^-5 watt-sec and the one sided power spectral density of the white noise ,N0= 10^-6w/hz then what is the o/p SNR of matched filter.
A single phase two winding transformer having rating: 20 KVA,480/120 V, 60 Hz A source connected to the 480 V winding supplies an impedance load connected to 120 V winding. The load absorbs 15 KVA at 0.8 pf lagging when load voltage is118 V.
Find the system transfer function H(s) = Y(s)/X(s) if the input x(t) and the output y(t) of the system are related by the equation y(t) + 3y(t) = x(t) - x(tau)d tau. Assume y(0) = 0.
Describe the operation of the series RC circuit. The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drops across the resistor and the capacitor at ver..
