1. Derive the sensitivity for a voltage and current source excited Wheatstone bridge.2. Show the balance condition for a Wheatstone bridge is also true in the sinusoidal steady state if the resistances are replaced with complex impedances.
A sequential circuit hast two inputs (X1 and X2) and one output (Z). The output begins as 0 and remains a constant value unless one of the following inputs sequences occur: (a) The input sequence X1X2 =01,00 causes the output to become 0
An a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at a frequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental, a 5th harmonic which is 10% of the fundamental and at a phase angle of 1.2
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
Compute the material dispersion of a wavelength 10nm lower than zero dispersion wavelength assumed to be 1300 nm.
A sequential circuit receives decimal numbers encoded in BCD one digit (4 bits) at a time, starting with the least significant digit. The circuit outputs are the 10's complement of the input number, also encoded in BCD least significant digit first.
The frequency response of the circuit is then expressed as a voltage divider involving Zeq and R: 1) Rewrite the equation above in the form: 2)Derive expressions for K, w_n (the corner frequency of an additional zero in the numerator due to the resis..
AnNMOS operating in triode region with Vds=0.1V conducts 60μA forVgs=2V. The device conducts 160μA for Vgs=4V. Calculate Vt. IfKn'=25μA/V2 , what is the device W/L What current would flow for Vgs=3V and Vds=0.15V
A three-phase delta connected load has a phase resistance of 15 ohms and a phase reactance of 17 ohms when connected to a 480VAC 60HZ line. What is the phase impedance, phase current power factor, and total power delivered to the load
desgin a BJT amplifier that is balanced in while having a single ended output. The differential gain is 20dB= 10 V/V, and CMRR is 40dB = 100 V/V. Beta is 100 and ro = 50kohm. use dual power supplies +Vcc and -Vee.
Make a user interface (using matlab) for amplitude modulation and demodulation without using the ammod and demmod function. The program should ask the user the 3 types of message signal (Square ,sinc,sinusoidal, triangle, sawtooth)
Assume that an antenna has a power input of 50 W and a gain of 30 dB relative to an isotropic radiator. Determine the increase in dB of the received signal at a point where the signal strength is 5 dB below the level of maximum radiation
Determine whether the foolowing discrete-time systems are causal or non cancausal, have memory or are memoryless, are linear or non linear, are time invariant or time varying. Justify your answer. In the following parts, x[n] is an arbitrary input..
