The Integrator and Differentiator appear to behave like analog filters. What kind of filters are they, how do they behave with low and high frequencies?
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
Discuss the factors that determine transformer efficiency. What are some sources of transformer losses and how can these can be reduced
Efficiency of MOSFET circuit provide in datasheets of any product is measured at transient state of my output node or staedy state?
A 1 W power source is connected to the input of a directional coupler with C=20 dB, D=35 dB, and an insertion loss of 0.5 dB. Find the output powers (in dBm) at the through, coupled, and isolated ports. Assume all ports to be matched.
An early code used in radio transmission involved using codewords that consist of binary bits and contain the same number of 1s. Thus, the 2-out-of-5 code only transmits blocks of 5 bits in which 2 bits are 1 and the others 0.
Write a function called Balloon that will accept a single variable named S. The function should replace S with the square of S and repeat this process until S is either greater than 10^15 or less than 10^-15.
A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.Write equation for modulated signal What is average transmitted power & modulation index
Consider a unity feedback control system with plant transfer function G(s) and controller transfer function Gc(s). (a) If the phase margin and crossover frequency are adequate but you need to increase the error constant.
The aim of this experiment is to develop a bipolar transistor amplifier with a voltage gain of minus 25. The amplifier must accept input signals from a source impedance of 1 kW and provide an undistorted output amplitude of 5 V when driving a 560..
Consider the circuit as shown below. If Vin peak voltage = 12V, Calculate the output voltage Vo. Open loop voltage gain of the Operational Amplifier A=10,000. The voltage drop across the diode is 0.7 V.
In a series RC circuit, R = 5 Ohms and C = 0.1F. The capacitor voltage is 10 volts at t=0. At t=0, a voltage of 4V is applied. a) Determine the total capacitance voltage and capacitance current as a function time after the external voltage is applied..
In a certain communications system a resonant-tuned circuit (tuned at 1200 kHz with Bandwidth = 15 kHz) is connected to the output of a non-linear amplifier (mixer). Find the frequency components at the output of the resonant-tuned circuit
