The equation y[n] - p y[n-1] = x[n] can be used to describe the value y[n] of a new investment by setting p = 1 + r/100 where r is the interest rate per period, expressed in percent.
Find the transfer function of this system and determine whether itcan be both stable and causal.
1. Calculate the mid-band gain-numeric and dB. 2. Calculate the three low frequency corners.3. Sketch the gain vs. frequency response a la Bode including asymptotes and approximate curve with all critical points defined in f and dB.
Consider a superheterodyne FM receiver designed to receive the frequency band of 1 to 20 MHz with an IF frequency 8 MHz. what is the range of frequencies generated by the local oscillator for this receiver
A line has an inductance of1.25mH/km with an impedance angle of 70 degree , and a capacitance to neutral of 0.01mF/km. Calculate its reactance and series impedance per unit length at 50Hz. Calculate the line admittance per unit length
A proportional control system is to be used to control the wing flaps of a jet air-plane. The wind load is expected to cause as much as 600 in .lb of torque. The system should be able to keep the flaps to within 5 of the set point.
The voltage magnitude of source 2 and the phase angles of the two sources is to be kept constant. Compute the complex power for each source and the line loss. Tabulate the reactive powers and plot Q1, Q2, and QL versus voltage magnitude jV1j.
The heating element in a soldering iron has a resistance of 30-ohm. Find the average power dissipated in the soldering iron if it is connected to a voltage source of 117 V rms.
A 60 Hz, three-phase, transposed transmission line has the following parameters: Z = 13.114+ j52.952, Y = j0.311/1000. The sending-end line-to-line voltage is 161 kV. The total receiving-end load is represented by ZL =143 with an angle
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LvDT and signal-conditioning output is 0.31 mV/mm with a +/-2 cm maximum core displacement.
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
Design a length-5 FIR bandpass filter with an antisymmetric impulse response h[n], i.e.., h[n]= -h[4-n], where (0 less tahn or qual n and 4 is bigger than or equal n), satisfy the following magnitude response values.
An op amp differential amplifier is built using four identical resistors, each havign a tolerance of ±5%. Calculate the worse possible CMRR.
Write an equation to help determine P-type body doping concentration Na for a required threshold voltage V (sub TN) for an N-channel Al-Sio(sub 2) -Si MOSFET. Use the equation to design an N-MOSFET with a thershold voltage of 10V
