Do you have the solutions for digital processing of speech signals book of Rabiner and Schafer.Questions: 2.14 and 2.17 of chap. 02 and questions 3.1 and 3.15 of chap. 03
Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether B is greater than A. The circuit has one output X, so that X = 1 if A = B.
A Si p-n-p transistor has impurity concentrations of 5´1018, 2´1017, and 1016 cm-3 in the emitter, base, and collector, respectively. The base width is 1.0mm, and the device cross-sectional area is 0.2 mm2.
Three cells whose open-circuit voltages are each V are connected in series. What is the open circuit voltage of the series connection If the same three cells were connected in parallel
A band filter has the following specs: Center frequency: 1500 Hz Bandwidth: 200Hz Chebyshev filter with a passband ripple of 1 dB 20-dB attenuation of te stopband gains at 1200 HZ and 1800 HZ. Determine the order of the lowpass prototype function.
Design a current divider that provides a 1:2 current split. Observe the current and power limitations. Another design constraint is that inserting current meters to measure the current division ratio must not upset this ratio
The treasure map in the figure gives the following directions to the buried treasure: "Start at the old oak tree, walk due north for 530 paces, then due east for 130 paces. Dig." But when you arrive, you find an angry dragon just north of the tree..
A single-phase half-wave rectifier is fed with a triangular signal with period 2 . The maximum positive and negative amplitudes are ± 12 V rms. determine: a) The value of the DC output voltage. b) The percentage of curly
The data inputs I0 through I7 are wired as follows: I0 = I1 = 0, I2 = I6 = , I3 = I5 = I7 = 1; and I4 = D. (a) Determine the Boolean function that the MUX implements. (b) Implement the function using a 4×1 MUX with minimum extra logic gates.
Consider DSB used to transmit an audio signal of 6kHz on a GSM phone with a carrier around 879MHz. By what factor is the Nyquist rate greater if you sample the DSB signal directly rather than the baseband message signal
How would you implement in the assembler a logical-shift-left(LSL) pseudo-operation for a machine that didn.t have this particular instruction Be sure your LSL instruction can shift up to W-bits where W is the machine word size in bits.
consider the circuit of fig. 5.59 for the case vcc vee 10v i 1ma rb 8komega and beta 100. find all dc currents
