Design a binary counter capable of counting to at least 84, the number of students in this class. It's OK to have excess capacity. The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asserted. Note that the counter should only change state, either to increment the count or clear to zero, on the rising edge of COUNT. You may use combinatorial logic gates and D flip flops. It is not necessary to display the output; just implement the counting engine.
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
Consider an 8-user CDMA system. The data vector of all users is given by [1,1,1,1,-1,-1,-1,1]. Find the total transmit signal.
A silicon sample at T = 300 K contains an acceptor impurity concentration of \(N_{A}\) = 1016 cm-3. Determine the concentration of donor impurity atoms that must be added so that the silicon is n-type and the Fermi energy is 0.20 eV
Design a common-emitter BJT amplifier with a gain of -100 (well above 3dB point) and a 3dB point at 100Hz. Assume beta = 100, Ic (quiescent) = 1mA, Vcc=20V. You can omit the output capacitor, but should bypass your emitter resistor.
the magnetic circuit shown with a mean core length of 52 cm and a cross sectional area of 18 cm^2. the length of the air gap is 0.14 cm. Determine the battery voltage required to obtain a flux density of 1.2 T in the air gap. Use the magnetization..
Given the starting address for the TC0 Interrupt is to become $5000. Write the assembly instruction necessary to place this ISR address into the interrupt vector table and then unmask the interrupt (assembly only).
Basics problems of Induction motor, The frequency of the induced rotor currents in the rotor of a 60 Hz induction, machine is 2 Hz. Furthermore, the fields in the air gap turn at -40 rpm with respect to the rotor.
In a balanced three-phase wye-wye system, the load impedance is 10 +j1 Ohms. The source has phase sequence abc and the line voltage Vab = 220 Vrms /30°. The load voltage is VAN = 120 Vrms /0°.
Determine the surface charge density on each conductor.
Important information about Examination of a digital radio link A. A digital radio link operates at a frequency of 75 MHz and uses ideal RRC filters with nroll off factor r = 0.2 in the transmitter
