Design a circuit to detect the the binary sequence 1010. The output from your design should be X = 1 iff the four latest inputs have been 1010. The output X=0 otherwise.Here is the input and output sequence that your design must generate:Clock: A B C D E F G H I J K L M N P Q RInput: 1 1 1 0 1 0 0 1 0 1 0 1 0 0 1 1 1X(out):0 0 0 0 0 1 0 0 0 0 1 0 1 0 0 0 0After the first four bits (ABCD = 1110above) are received, the output X = 0,until the bits CDEF are received (1010 above), so for clock period F the output X = 1, because the last three inputs were 101 (at clocks BCDE above), and the current input is 0, and also X=1 for input sequences HIJK and JKLM.
a) Draw the state diagram
b) Draw the schematic for the logic to implement this circuit using Inverters, AND gates, OR gates and D flip flops. Use the reverse side and additional sheets if needed.
Signal Definitions are A.H, B.L ,C.L, D.H and Z.L. It is recommended you apply DeMorgan's Theorem first to the above equation. Draw (on paper) a circuit diagram implementing Z, using the minimum number of gates.
Understanding low, high and band pass filters, A signal in the IF section of an FM radio receiver occupies the frequency band 10.61 MHz to 10.79 MHz. Compute the bandwidth of this signal.
1. Determine the wavelengths for electromagnetic waves in free space with the following frequencies: 1 kHz, 100 kHz, 1 MHz, 1 GHz. 2. Determine the frequencies for electromagnetic waves in free space with the following wavelengths: 1 cm, 1 m, 10 m..
a) At what time does the peak value of the AC signal occure b) What is the frequency,f,of the AC signal c) What is the period,T,of the AC signal d) At what time does the negitve peak value of the AC signal occur
Baseband digital trnamission and multi level coding, A baseband digital data link transmits polar binary NRZ current pulses at a rate of 1.0 Msps. The link uses ideal RRC filters with roll off factor r = 0.5.
A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.
You want to download a 5 Mbit file over a 10-Mbps Rayleigh fading channel in the 1800 MHz frequency band. You are traveling at 6 km/h and use 1000-bit packets.
The signal m(t)=6sin(2*pi*t) volts is transmitted using 4-bit binary PCM system. The quantizer is of the midriser type, with a step size of 1v
(a) Design a circuit that provides an output voltage which indicates the amount of fuel remaining, so that 1 V=empty and 5 V=full. (b) Design a circuit to indicate the rate of fuel consumption by providing a voltage output calibrated to yeild 1V = 1..
Absorption loss of metal shielding, A plane metal shield offers an absorption loss of 30 dB at a frequency of 10 kHz to normally incident radiated emission.
A rectangular chip has a top surface of 0.5 cm by 2 cm cooled by air at 20 oC with h = 150 W/m2.K. There are also 16 connector pins, 1 mm wide, 0.5 mm thick, 6 mm long and k = 60 W/m.K attached to a circuit board at 30 oC.
