Explain the use of hardwired control unit in digital signal processing.1 AnswerConsider the signal -GATE EC 20151 AnswerSuppose x[n] is an absolutely summable discrete-time signal. -GATE EC 20151 AnswerA company needs to develop digital signal processing software for one of its newest inventions. The software is expected to have 40000 lines of code. The company needs to determine the effort in person-months needed to develop this software using the1 AnswerWhat is batch processing What are the steps involved in batch processing List any two advantages disadvantages of batch processing?1 AnswerA sinusoidal message signal is converted to a PCM signal using a uniform quantizer. The required signal-to-quantization noise ratio (SQNR) at the output of the quantizer is 40dB1 AnswerWhich one of the following statements about differential pulse code modulation (DPCM) is true?1 AnswerIn the system shown in figure (a), m(t) is a low-pass signal with bandwidth W Hz. -GATE EC 20151 Answerhe number of levels in the quantizer is ____________________ -GATE EC 20151 AnswerConsider the following amplitude modulated signal: s(t) = cos(2000 πt) + 4 cos(2400 πt) + cos(2800 πt). The ratio (accurate to three decimal places) of the power of the message signal to the power of the carrier signal is __________.0 Answer A company needs to develop digital signal processing software for one of its newest inventions.-gate-cse-20111 AnswerProcessing times (including setup times) and due dates for six jobs waiting to be processed at a work centre are given in the table. The average tardiness (in days) using shortest processing time rule is (Gate 2018 Mechnanical engineering)0 AnswerAn 80 Hz seismic signal is sampled at a rate of 100 samples/s. What will be its aliased period (in seconds) in the sampled signal? (-Gate geology and geophysics 2014)1 AnswerSignals from fifteen thermocouples are multiplexed and each one is sampled once per second with a16–bit ADC. The digital samples are converted by a parallel to serial converter to generate a serial PCM signal. This PCM signal is frequenc1 AnswerConsider the following solution to the producer-consumer synchronization problem. The shared buffer size is N. Three semaphores empty, full and mutex are defined with respective initial values of 0, N and 1. Semaphore empty denotes the number of available slots in the buffer, for the consumer to read from. Semaphore full denotes the number of available slots in the buffer, for the producer to write to. The placeholder variables, denoted by P, Q, R, and S, in the code below can be assigned either empty or full. The valid semaphore operations are: wait() and signal().0 AnswerLabel the Digital signal and Analog signal with the help of a diagram. (MUSIC-AESTHETICS-CBSE-2018)1 AnswerThe transmitted signal in a GSM system is of 200 kHz bandwidth and 8 users share a common bandwidth using TDMA. -GATE EC 20151 AnswerDuring an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station? The signal travels at the speed of light, that is, 3×10^8 ms-1. - Physics Cbse class 11 1 AnswerWhat is information-processing model?1 AnswerWhich one of the following statements is true with regard to processing and presentation of protein antigens?
