1) Signal x(t)=2cos⁡(πt+π/4) is sampled at 10 Hz sampling rate. Represent output in discrete time sequence x[n]. Also, find the digital frequency ω in rad/sample. 2)A dual channel audio signal x(t) is sampled at 16KHz. Each sample is later represented using 16- bits of each. Calculate data rate of output of A/D converter. If allowable range of input is ± 2.5 Vpp then calculate resolution of the ADC chip and SQNR of it.
