Sketch the waveform of the following signal: x(t)=del(cos t)

Determine the inverse z-transform of X(Z)=e^z, ROC:all z except |z|=infinity

. Consider the variability of the vowel characteristics among speakers. If humans can create a phoneme from similar vocal tract shapes, but with different speaker identifiability, then the source and prosody must play a large role in speaker characteristics, as well as the vocal tract. A ventriloquist, for example, can keep his/her vocal tract in roughly the same shape (i.e. for a particular phoneme), yet mimic different voices. Offer an explanation in terms of source and prosodic characteristics.

a series resonance network consisting of a resistor of 300 ohms ,a capacitor of 120 micro f and an inductor of 20 mh is connected across a sinusoidal supply voltage which has a constant output of 9v at all frequency.calculate,the resonant frequency,the current at resonance, the voltage across the inductor and capacitor at resonance, the quality factor and the bandwidth of the circuit.also sketch the corresponding current waveform for all frequencies

A series RLC circuit consists of a 20 Ω resistor, a 51 μF capacitor, and a 25 mH inductor. If the source frequency is 50 Hz, and the circuit current is 350 mA, what is the applied voltage?

A mild steel ring having cross sectional area of 5 cm square and mean circumference of 40 cm has coil of 200 turns wound uniformly around it calculate reluctance at required to produce flux of 800ùrwb Assume ùr for mild steel to be 380 at flux density developed in core
