(a) Design a high-pass filter with a cutoff frequency of 40 kHz. Use 0.01 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at the cutoff frequency? Give your answer both as ratio (Vout/Vin) and in dB. D) What is the gain of the filter at a frequency of 55 kHz?
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.
2. Compute the symbol error probability for both constellations in terms of the Gaussian error integral Q(x). 3. Compute the bit error probability for both constellations in terms of the Gaussian error integral.
The contects of a six-bit register are initially 100101. The register is shifted four times to the right, with the serial input being 1101. What are the contents of the register after each shift
Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV. If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifi..

Determine the value of the output voltage due to the voltage source only (Vol), and due to the current source only (V02).
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
An Air capacitor consisting of two closely spaced parallel plates has a capacitance of 1000 pF. The charge on each plate is 1 micro C. What is the potential difference between the plates. If the charge is kept constant.
