Current assets equal $210,000, of which $5,000 consists of prepaid expenses. The remainder of current assets consists of cash, accounts receivable, marketable securities, and […]
In Section 6.8 we derived the formula for the bit In Section 6.8 we derived the formula for the bit error rate of non-coherent binary FSK as a special case of non-coherent orthogonal modulation. In this problem we revisit this issue. As before, we assume that binary symbol 1 represented by signal S1 (t) is […]
Question: Prove the following two properties of the autocorrelation function R X (?) of a random… Prove the following two properties of the autocorrelation function RX(?) of a random process X(t): (a) If X(t) contains a DC component equal to A, then RX(?) will contain a constant component equal to A2. (b) If X(t) contains […]

In Section 4.11 we studied the eye diagram of a In Section 4.11 we studied the eye diagram of a quaternary (M 4) PAM baseband transmission system under both noisy and band-limited conditions. In that experiment, the channel was assumed linear. In a strictly linear system with truly random data, all the eye openings would […]
In Section 3.7 we described line codes for pulse-code modulation In Section 3.7 we described line codes for pulse-code modulation. Referring to the material presented therein, formulate the signal constellations for the following line codes: (a) Unipolar nonreturn-to-zero code (b) Polar nonreturn-to-zero code (c) Unipolar return-to-zero code (d) Manchester code
1. Dillner Company uses an activity-based costing system with three activity cost p 1. Dillner Company uses an activity-based costing system with three activity cost pools. The company has provided the following data concerning its costs and its activity based costing system: The “Other” activity cost pool consists of the costs of idle capacity and […]
Single-sideband modulation may be viewed as a hybrid form of Single-sideband modulation may be viewed as a hybrid form of amplitude modulation and frequency modulation. Evaluate the envelope and instantaneous frequency of an SSB wave for the following two cases: (a) When only the upper sideband is transmitted. (b) When only the lower sideband is […]
A DSB-SC modulated signal is demodulated by applying it to a A DSB-SC modulated signal is demodulated by applying it to a coherent detector. (a) Evaluate the effect of a frequency error ?A? in the local carrier frequency of the detector, measured with respect to the carrier frequency of the incoming DSB-SC signal. (b) For […]
A DPCM system uses a linear predictor with a single A DPCM system uses a linear predictor with a single tap. The normalized autocorrelation function of the input signal for a lag of one sampling interval is 0.75. The predictor is designed to minimize the prediction error variance. Determine the processing gain attained by the […]
