Derive the transfer function for a system with an function u(t) and an ouput function x(t) described by the following differential equation:d^3x/dt^3+5d^2x/dt^2+17dx/dt+13=d^2u/dt^2+5du/dt+6
Show that the complex envelope of the sum of two bandpass signals (with the same carrier frequency) is equal to the sum of their individual complex envelopes.
Find the capacitance C for the partially-filled spherical capacitor consisting of an inner conducting sphere of radius a and an outer conducting sphere of radius c with the region a<r<b filled
A speech signal with bandwidth B= 10 Khz is sampled at F2 = 20 KHz. Suppose that the signal is corrupted by four sinusoids with frequencies. F1 = 10,000 Hz ,F2 = 8889 Hz, F3 = 7778 Hz , F4 = 6667 Hz
Design a low pass filter of gain 40 dB and corner frequency is 60 Hz assuming signal has a source of resistance = 100 ohms ( YOU want error propagation in pass band to be < 5% .
The display needs to tell you what direction you are about to move. The problem is WBNEC insists that you use a standard 7-Segment display. (Hint: You can tilt the display.) Design a decoder that wi
A 5000-Ω resistor and a 50-μF capacitor are connected in a series at t = 0 with a 6-V battery. The capacitor is initially charged. what is the current in the circuit at t= 0, and at t= 5, a
If I put a short in across the terminals a and b, does that mean the Isc = 0 since the capacitor would eventually charge and thus become an open circuit If so, how to do you find Vt and Rt
show that for a square matrics the linear dependence of the row vectors imples the column vectors.conversely for a non square matrics either row vectors or column vectors are linear dependent.
Write a program to blink the last 3 digits of your social security number on 3 bits of Port B. For example if the last 3 digits are 654 then bit 2 of Port B should blink 6 times, bit 1 should blink
A sequential circuit for a luggage lock has ten pushbuttons labeled 0,1,2,3,4,5,6,7,8 and 9. Each pushbutton 0 through 9 produces a 1 on Xi, i = 0 through 9, respectively, with all other values on v
Consider a signal g(t) which is the time-reversed real signal f(t), so g(t) = f(-t). Let g(t) have Fourier series coecients, cn. How are the Fourier series coefficients, cn and dn related
Find an expression for the potential at any point (x, y), assuming zero volts on the z-axis. When calculating the potential, you may start with the potential of a single infinite line charge, assume
