Question

Need help please!

An analog signal with a bandwidth of 12.5 kHz and an average power of 50 mW is to be transmitted by PCM. What is the sampling rate required to quantize this signal at twice the Nyquist Sampling Rate? Using a uniform quantizer with a plusminus 5 volt input range determine the minimum number of bits required for a SQNR of 35 dB. Using a quantizer with a plusminus 5 volt input range, and a mu-law compandor with mu = 255, determine the minimum number of bits required for a SQNR of 35 dB. Based on the results of parts B and C, what is the minimum bit rate for PCM transmission. What is the minimum transmission bandwidth required for this binary baseband signal? This binary signal is used to produce the frequency-shift keyed signal phi FSK =Ac cos(2 phi f ct+ 2 pi k f plusminus 5 dt) where plusminus 5 V corresponds to a logical 1 and -5 V corresponds to a logical 0. Select Ac, fc and kf to produce an FSK signal with a nominal 1 MHz carrier frequency, a frequency deviation of 50 kHz and an average power of 1 kW Sketch the FSK signal for the input 110. Sketch a block diagram of a system to demodulate the FSK signal. The binary signal has the power spectral density shown below. Power Spectral Density of Binary Signal Write the equation for the bandwidth of the FSK signal.
