The bandwidth of a digital communications channel is limited to 40 MHz. Calculate the maximum data rate for each of the following digital communications schemes. Assume that NRZ (rect) pulses are used for signaling. a. ASK b. FSK with Ife, -fc₂l = 4 MHz c. BPSK (binary PSK or 2-PSK) d. QPSK (quaternary PSK or 4-PSK) e. 16-QAM f. 64-QAM The following is an 8-bit word to be transmitted over a comm. channel: [10110010]. The data rate is 1Mbps = 10 bits per second. Assume that a common amplitude A = 2V and NRZ (rect) pulses are used for signaling. If the carrier frequency (when applicable) is 2.45GHz, sketch the transmitted signal (indicate amplitudes and instantaneous frequencies and phase changes where applicable) corresponding to each of the following schemes: a. ASK b. FSK with one-sided deviation Af = 10MHz C. PSK Also estimate the bandwidth for each signal. The bandwidth of a digital communications channel is limited to 40 MHz.
