Design an ac-dc voltage converter based on half-wave rectification and filtering. The requirements are: 1. Choose the values of the load resistor R and the capacitor C so that the converter will have a ripple factor of 10% 2. R should be in the single digit kilo-ohm range 3.Determine the dc level 4.Use the idealized diode model with a 0.7 V offset voltage The ac signal is V(t)=10sin120Pi(i) volt
our senior design team is designing a force sensor to measure a force signal and analyze the signal with a microcomputer (binary system). The analog force signal is between 10 N and 70 N and has the frequency bandwidth of DC - 1000 Hz.
In a typical AC circuit, the supply voltage is 10 VPK and frequency is 60 Hz. If the current through the system is 2 APK with a phase angle of 60o, then the power dissipated by the source is
Explain the structure and nature of the ionosphere with reference to daily, seasonal and long-term changes and explain the modes of propagation of radio waves of different frequencies
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 10 , inductive reactance XL = 20 , and a capacitive reactance XC = 10 . All three components are connected in parallel to the source.
A sequential circuit has two inputs w 1 and w 2 , and an output, z. Derive a suitable circuit for the given condition.
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).
Instantaneous voltage and current of capacitor, The current flowing through a 5 F capacitor is i=3e^-2t. What is the voltage as a function of time, if the initial voltage is zero?
Bandwidth, In a given communications system, one signaling element is used to represent 64 bits. The required data rate is 1.789 Mbps.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Design a 16 bit x 16 bit combinatorial multiplier. Use a topology similar to the 4x4 multiplier.
(b) If the molecular weight of bombykol is 238.4 amu, what is the molecular formula (c) If 5.698 g of bombykol is burned in excess oxygen to form 16.83 g of CO2 and 6.452 g of H2O, how many grams of carbon were present in the original sample
