Design a decade counter (negative edge-triggered counter) using flip flop circuit that can be used to perform binary counting. Show the timing diagram for the input and four outputs of the decade counter. Note that the counter output cycles back to 0000 after 1001. Cascade four counters in order to counts in power of 10. Use seven-segment LED display to view the output (driven by decoder).
What is the BER at the output of the receiver in clear air conditions, and the average time between errors? Give your answer in years, days, or hours as appropriate. Assume an implementation margin of 0.5 dB.
calculate the minimum sampling interval (time period for counting the pulse train) to achieve a speed resolution of 5 rpm, and the number of bits that must be there in the binary counter if the pulse train is to be sampled with this interval for a..
Calculate the %age second harmonic distortion present in the amplifier's output for a sinusoidal input of 10 mV r.m.s.
The op-amp circuit measures the changes of temperature in a system. The output voltage is given by v0(t) = -R(t)vi(t). Suppose that the temperature in the system changes cyclically after t = 0, so that R(t) = [1 +0.5 cos(20πt)] u(t) and let the in..

Explain and discuss the problems presented by electronic discovery in civil actions and how the law has responded.
A capacitor is used in the electronic flash unit of a camera. A small battery with a constant voltage of 6 V is used to charge the capacitor with a constant current of 10 microamperes. How long does it take to charge the capacitor
Prepare an Excel graph showing the individual components and summated resultant waveform of the odd harmonic series resulting in an approximate square wave.
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
Draw a labeled sketch of x(t) over a few periods: be careful, make sure you follow the exact definition of x(t)
Assume that capacitor is completely discharged when t
