A digital circuit should produce a 1 to sound a warning if a seat belt is unfastened when the key is in the ignition and someone is sitting in the seat. The input SeatBelt is true if the seat belt is fastened. The input Key is true when the key is in the ignition. A sensor generates true for the signal Person when it detects weight on the seat indicating that someone is sitting in the seat. Write an equation for this function using the signals SeatBelt, Key, and Person I keep struggling with this function from the truth table. I appreciate the help.

What would the boolean expression be for the following kmap?

A continuous signal x(t) is 2 seconds long. The first second of the signal contains music while the 2nd second is total quiet. The sampling rate is 1000 Hz. If the entire signal is input into the FFT what is the minimum resolution that can be resolved between frequencies? The total number of samples in the 2 second segment are: The bin increment is The minimum frequency that can be resolved is hz. hz

A signal with 256 symbols is transmitted by 10 symbol per second. a) What is the information rate R? b) Can the output be transmitted without error over AWGN channel with B- 10 KHz and SNR 100 c) Find the SNR required for error-free transmission for part (b) d) Find the B required for AWGN channel for error-free transmission if SNR 100

The waveform diagram below shows a sample set of input waves for a 7474 IC. Analyze the input waveforms and solve for the Q output waveform (Draw the output waveform on the graph). Answer the following questions 1 3 4 10 11 12 CLK PRE PRE HD CLR CLK-O D HIGH Q LOW 1. When does the D Flip-Flop shown effect a moving the status of the inputs to the outputs? The High level of the Clock Pulse The Low level of the Clock Pulse The Rising edge of the Clock Pulse The Trailing edge of the Clock Pulse What Mode of operation is the Q output of the D flip flop in at the 12 indicated points in the waveform, I don't mean is it high or low, but WHY is it high or low. 1. 5. 9. 2. 6. 10. 3. 7. 11. 4. 8. 12.

A signal with frequency 1902 Hz is sampled at a sampling rate of 13797 Hz. Then the repetitive frequency of the signal assuming that the sampling frequency is doubled is. O 9993 O 23790 O 3094 O 16892
